Nick Jonas proved that "healthy living" certainly does a body good after posting his surprising — and much-talked-about — shirtless selfie that sent the Internet ablaze, and for that, you can thank Kevin and Joe.

"It took one day to put it up," Nick told Ryan Seacrest's radio show. "I debated with my brothers and people in our band like, 'Should I do this?' They were like, 'You have to, you have to,' so I did it."

The photo, which Jonas said he only took once, currently has more than 213,000 likes on Instagram, with not only fans, but celebrities swooning over his washboard abs.

"The more shirtless selfies @NickJonas posts, the better my day gets," Neil Patrick Harris tweeted.

"No, I didn't really to be honest," Jonas said in response to whether he thought the picture would spark such reaction. "Like I said in the picture, I never do that, and there are a lot of people running around without their shirts on these days so I didn't want to just add to the noise, but I felt like as a diabetic its twice as hard to stay in shape...so I just wanted to be an inspiration to those people...it's been a pretty hilarious reaction"

Yet, there is still one question that many JoBro fans have been wondering: who took the now famous photo?

"That was the funniest part of the reaction people trying to figure out who took it," Jonas said. "And it was me, there is a self-timer setting on the camera app that I use, ...

"I probably went through five or six drafts of that letter over three days, even though it's only a few paragraphs; it's tough, deciding how much you want to let people in," Panic! at the Disco drummer Spencer Smith says. "I ended up leaving in more than I guess I thought I would, and in a lot of ways, it was freeing ... if you try to pull the wool over people's eyes, even if it works, it doesn't feel good inside."

He's talking, for the first time, about the letter he wrote to fans earlier this week, in which he revealed that, for year's he'd abused alcohol and prescription medications, and recently sought treatment for his addictions. And though he revealed much in that letter, it turns out he's still got plenty to say.

Next week, we'll be bringing you more of our interview — where Smith discusses how his addictions nearly got him kicked out of Panic!, and how he plans on remaining sober as the band returns to the road — but today, we'll start at the very beginning: the incident that drove his use of prescription pills into overdrive, and started him on his downward spiral.

"I didn't mention it in the letter, but two-and-a-half years ago, my dad was diagnosed with ALS. I was actually introduced to painkillers and Xanax a little bit before that, and then it just increased when that happened and I became aware of what he was dealing with," Smith says. "Initially I was taking them just like any other drug; ...

Since bursting onto the scene in late December of 2012, Trinidad James has made the best of his golden opportunity. The 25-year old Atlanta MC stepped into the spotlight with "All Gold Everything," one of the biggest street-anthems of recent years, but that doesn't mean making it big — and becoming MTV's Artist to Watch — was easy.

When MTV News caught up with James last month, he provided some advice to those taking the steps of the quote-unquote "come-up," or in his case the "turn-up."

"I had to do a lot of growing up, a lot of soul-searching. The industry is way more than what you think it is," he said, explaining that the rap game is no cake walk, and that he's had his own share of criticism.

"When you're actually really in it and you strive to be the person that you are, and not confined to you know whatever people want you to be, it's not easy, so I've been learning a lot and still am right now," he added.

He isn't alone in the process, though. James is currently touring with some of hip-hop's brightest stars in Wiz Khalifa, A$AP Rocky, B.o.B and Joey Bada$$ on the Under the Influence tour. "I met some new people that rock with me and are down for me," he said. "They got my head right."

In the end, he left us with some inspiring albeit vague advice: "Dream, believe and turn up. And you can take that however you want to."

Busta Rhymes has been interested in the dynamics at work behind secret societies for some time now, but even he thinks that hip-hop's fascination with the Illuminati is spiraling out of control. During his visit to "RapFix Live," Busta explained why he addressed the topic on his upcoming album E.L.E. 2, adding that it was surreal to hear Jay Z being questioned about it during a radio interview.

"I've always been intrigued by the concepts, ideas and the possible realities of secret societies, hierarchy governments and people that really pull the strings that you don't see," Busta explained. "That's been a lining in all of my albums, that's why they're called The Coming, When Disaster Strikes, E.L.E., Anarchy, etc."

"When you talk about these things and it stirs conversation that's one thing. But within the last four years, it became mainstream American dialog. When you can listen to Angie Martinez interview Jay Z on Hot 97 and ask if it's true that he's a member of the Illuminati...it's so funny to me to hear that on a radio station of that format, early in the afternoon, being asked to a fellow Brooklynite from Marcy Projects — that has gotten to a level of profound success and accomplishments — if he is an Illuminati member."

Busta, who says he's a "diligent researcher" of the subject, adds that it's important to have the conversation, but that conversation needs to be grounded in reality. "I think the perspectives need to be fined tuned, so that there is proper understanding. If that isn't ...

Kanye West has re-imagined as his very own dark twisted fantasy. The rapper put his stamp on the trailer of the Lindsay Lohan-starring noir. Calling it the "DONDA Remix," it includes a brand-new score and coloration.

Yeezy worked with editor Nate Brown, updating the look of the trailer, including making the colors brighter and changing up the graphics.

While the shots included in this updated trailer remain virtually the same as the original, the pacing feels different, thanks to the sounds of West and audio engineer Noah Goldstein.

The new track features a heavy piano and sparse beat. The pace builds, and more notes are added, as the drama of the trailer begins to crescendo. As the trailer nears its end, the volume gets louder and a scratchy effect etches into the piano beat. Instead of including the full credit marque like in the original trailer, Kanye's version ends with a sparse, all-white screen featuring the movie's website.

"The Canyons" was written by "American Psycho" scribe Bret Easton Ellis. The twosome teamed up on the promo video for West's Yeezus track "New Slaves," which re-imagined Ellis' iconic 1991 novel with reality stars Scott Disick and Kim Kardashian's bestie, Jonathan Cheban.

When MTV News spoke to Ellis about their collaboration on that project last week, he teased that he and Yeezy were hard at work on something else, but wouldn't say what it was. All he could reveal was, "And then Kanye and I have been meeting about writing a script for him and so that's a project that's kind of ...

We still may not know what's in that gold truck driving across the country, but we do know that Katy Perry's new single is called — "Roar."

It had been rumored earlier this week that Perry's lead Prism single would be titled just that... and the singer confirmed it Friday (August 2), sharing it will debut on August 12.

In the dark announcement clip, Perry wears a choker, striped sweater and dark lipstick, a pulsing hum serving as the soundtrack. She then takes a lighter and holds it up to her signature blue wig, worn during her . As the wig burns up, the camera pans out to reveal Perry in full-on badass mode. The words appear onscreen in tiger print.

Perry had one additional message for her Katy Cats, tweeting, "WE DON'T NEED NO WATER LET THE BABY BLUE BURN."

Little else is known about the song, but it's rumored that Dr. Luke, Max Martin and Bonnie McKee have a hand in its creation. In fact, McKee may have inadvertently given MTV News a vital clue about the track last month.

"I think it's a little bit more grown up and it's really interesting," said McKee, who had worked with Katy on "California Gurls." "I'm really excited for the world to hear it because she's just... she's taking a new approach. And I don't want to say too much about it, but it's definitely different. It's definitely a little more mature than the 'California Gurls' of yesterday."

"Roar" drops one week before Lady Gaga will release her new single ...

Lady Gaga has worn many, many, many looks over the course of her eye-popping career, but her newest makeover, in the new trailer, might be her most unexpected to date.

In the latest trailer, which premiered Friday (August 20), a gun-toting Cuba Gooding Jr. appears on the screen, saying, "You've seen my face."

Gooding Jr. then peels off the synthetic face to reveal Gaga lurking underneath the surface, wearing a strapless red outfit, complete with bright-yellow blond hair, looking a bit like her killer .

"Muy bien, indeed," says Gaga, who will play Lady Chameleon in the flick. The camera then closes in on Gaga's face as she offers up sultry gaze.

The film, from director Robert Rodriguez, also features a who's who of actors including Danny Trejo in the title role, as well as Carlos Estevez (better known as Charlie Sheen) playing the president of the United States. The film boasts appearances from Vanessa Hudgens, Sofia Vergara, Mel Gibson, Antonio Banderas, Jessica Alba, Amber Heard and Michelle Rodriguez.

"Machete Kills," the sequel to 2010's "Machete," opens in theaters on September 13, and marks Gaga's big debut on the big screen. And three weeks before she premieres the flick, she'll take the stage at the 2013 MTV Video Music Awards, where she will perform her new single, "Applause," off her November 11 album release, ARTPOP.

Gaga will release the song and video for , giving her Little Monsters just enough time to learn all the words before she performs it live at the Barclays Center in Brooklyn at ...

Nothing is what it seems in Icelandic director Baltasar Kormákur's gritty "2 Guns," a film that puts undercover agents played by Denzel Washington and Mark Wahlberg against each other before letting them loose on those who did them wrong. Based on the Boom! Studios limited series of the same name by Steven Grant and Mateus Santolouco, "2 Guns" seems primed to give moviegoers a late-summer palette cleanser following a season full of big-budget bombs.

While critics seem divided on whether or not "2 Guns" manages to be anything more than a throwback to '70s conspiracy-laden crime films, most critics can agree that Washington and Wahlberg bring an A-game befitting A-list stars. The supporting cast — consisting of Bill Paxton, Paula Patton, James Marsden, and Edward James Olmos — receives just as much praise as the film's two big guns, with each actor reveling in every old school double cross and standoff.

Read on for a sample of "2 Guns'" reviews.

Scene-Stealing Support
"[Mark Wahlberg and Denzel Washington are] two of the most reliable, relatable action heroes in American movies today. In '2 Guns' the company they keep on screen is solid, thanks to Bill Paxton as a vicious CIA operative after the millions stolen from a New Mexico bank; Edward James Olmos as a drug lord, after the same; James Marsden, as a U.S. Naval Intelligence officer, after the same." — Michael Phillips, Chicago Tribune
