It's tempting to think that Jack Johnson was swinging in a hammock, strumming a guitar and staring at a sweating, fruity drink when the call came. But whatever the beach bum rocker was doing, he jumped up and quickly answered when asked to fill in for Mumford & Sons after the band had to drop out of their headlining set on Saturday at the Bonnaroo festival.

"I was on my way to Bonnaroo to sit in on a set with my friends ALO last night when we got the call asking if I could possibly help out and cover for Mumford and Sons," said Johnson in a statement about his last-minute main stage gig. "I heard the news about Ted Dwane and was happy to know that he was on his way to recovery."

Mumford were forced to cancel
 their headlining slot following the hospitalization of bassist Dwane this week to remove a blood clot
 from his brain. Earlier this week they postponed two Texas gigs and made no mention of whether they would still play 'Roo.

Though happy to step up, Johnson said the main stage audible did require a bit of scrambling on his behalf. "I called my band and asked if they were up for it," he said. "Long story short - they are headed this way. I've got a lot of lyrics and chords to relearn by Saturday night. I was here to play the first Bonnaroo and it is a very special festival to my band. We are excited to hit the stage again. ...

Miley Cyrus' parents, Billy Ray and Tish Cyrus, are divorcing after 19 years of marriage. The couple confirmed the news on Thursday.

According to People, Tish filed for divorce from her singer husband on Thursday in Los Angeles Superior Court citing irreconcilable differences. They have five children together, including 20-year-old Miley. She's looking for primary custody of their daughter, Noah, 13, as well as spousal support.

"This is a personal matter and we are working to find a resolution that is in the best interest of our family. We ask that you respect our privacy at this time," she said in a statement.

In his own statement, Billy Ray added, "This is a personal matter and we are doing what is in the best interest of our family. We ask that you respect our privacy at this time." Sources tell E! News that he has also filed paperwork in Nashville. Billy Ray is best known for his 1992 hit "Achy Breaky Heart," but re-launched his career and kickstarted Miley's with the hit Disney show "Hannah Montana."

On Thursday, their superstar daughter tweeted, "@billyraycyrus since your text and email obviously aren't working would you like to talk like this?"

This isn't the first time Miley's parents have split up. The couple separated in October 2010 , but in March 2011, they confirmed they were reconciling. "I dropped the divorce," he said on "The View." "I wanted to put my family back together."

Miley is currently readying her 2013 album release. Last week she dropped the Mike Will Made ...

Director Sofia Coppola is no stranger to stories examining the emotional vagaries of fame. She's returning this week with her fifth feature film, "The Bling Ring," a fictionalizes the true story Los Angeles teenagers who successfully burgled the home of dozens of celebrities, including Lindsay Lohan, Paris Hilton and others.

The film takes a dispassionate but incisive look at a world where value is derived from how much time a person spends in the public eye. But do critics think that dubious fame is a good subject to be explored, much less by a filmmaker who herself comes from a famous family?

Suffice it to say that critics thus far are divided on the film, some celebrating its arm's length portrait of social climbing, and others criticizing its lack of, well, criticizing its characters and its subject. But as you're deciding whether to watch Coppola's latest, take a look at some of the opinions MTV News culled from around the critical community, to see if the film's approach sounds like something you'd like to see.

What Do Longtime Supporters Think Of Coppola's Latest?
"Until now, I have loved every one of Coppola's movies: I love her sure and delicate touch, and she's better than any other contemporary filmmaker at capturing the greatness of small moments. 'The Bling Ring' is the first of her pictures that I actively dislike — I sense no mystery, no depth there." — Stephanie Zacharek, The Village Voice

He can leap tall buildings in a single bound, but can Superman clear $100 million in a single weekend?

That's the question on the minds of box-office watchers looking ahead to a weekend that will obviously be dominated by the Superman reboot with which DC Comics owners Warner Bros. are hoping to launch a new franchise. After all, "Iron Man" eventually led to which is now the third largest movie of all time. Why wouldn't Marvel's longtime rival want a $1 billion blockbuster, too?

There's no question as to whether or not "Man of Steel" will be big. The question is how big.

After the creative and commercial misfire of "Green Lantern," Warner went all out by pairing "300" director Zack Snyder with "Batman" franchise masterminds Christopher Nolan (as producer and story collaborator) and screenwriter David S. Goyer to reboot the Kryptonian hero. They also spent a reported $225 million making the movie, to say nothing of the huge marketing rollout. "Man of Steel" kicks off with the second widest release for a non-sequel ever in more than 4,200 locations.

"Man of Steel" kicks off with the second widest release for a non-sequel ever in more than 4,200 locations. Speculation over the opening-weekend prospects has been more energetic and more varied than any tentpole film in recent memory. Warner Bros. kept their own official weekend projection in the pretty conservative $75 million range. Noting Fandango's report that "Man of Steel" led all other summer films in advance ticket sales, EW.com predicted $132 million. BoxOfficeMojo.com not ...

We already know there are no pre-orders for Kanye West's Yeezus.


And, amazingly, the just five days before the beginning of 
 the album hasn't leaked, so the remaining question is: what songs made the cut?

As the countdown dwindles, an unconfirmed track list has surfaced that appears to conform to the news we know so far about the top-secret project
 executive produced by hip-hop legend Rick Rubin and previewed earlier this week at a New York listening party.

According to the reports, the album opens with "On Sight," then comes "Black Skinhead" and "I Am a God," with a feature from "God." One of the songs 'Ye has previewed live, "New Slaves," has a feature from Frank Ocean, while, as previously reported, "Hold My Liquor" comes with help from fellow Chicagoan Chief Keef and Bon Iver singer Justin Vernon.

Track six of the 10-song album is "I'm In It," with a sample of Kenny Latimore's "Lately," according to what is apparently the leaked liner notes on the back of the art-less clear CD casing. "Blood On the Leaves" has a sample of Nina Simone singing Billie Holiday's iconic "Strange Fruit" and "Guilt Trip" with Kid Cudi interpolates the Lord of the Underground's "Chief Rocka."

Chicago drill sergeant King L shows up on "Send It Up," which appears to have a sample of dancehall king Beenie Man's hit "Memories." The whole thing comes to close with "Bound 2," featuring Gap Band legend Charlie Wilson.

At press time a spokesperson for West had not returned requests for comment on the track listing.

MANCHESTER, Tennessee — Mumford & Sons have canceled their headlining performance at the 2013 Bonnaroo Music and Arts Festival. The announcement comes following the hospitalization of their bassist, Ted Dwane, this week to remove a blood clot on his brain.

The band wrote Thursday night on its Facebook page, "It is with sadness that we have to announce the cancellation of our scheduled performances at both Bonnaroo and Telluride Festivals ... If we could've we would've, you know that about us. We trust that you can respect our collective desire to encourage Ted to make a full recovery, and that this is based purely on the medical advice we have received."

The band also reported that Dwane has been discharged from the hospital and his medical team is "very pleased" with his recovery.

No word yet on who will replace Mumford & Sons, who were scheduled for a two-hour set on the main stage Saturday night.

The guys remained lighthearted in their announcement, joking, "[Dwane] has been nothing short of heroic in how he has handled the whole ordeal, and now it has been medically proved that he does indeed have a brain."

SPOILERS AHEAD

From the first trailers that were released for the film, "This Is The End" featured a number of sizable cameos. Aside from the core castmembers, including Seth Rogen, Jay Baruchel, James Franco, Jonah Hill, Craig Robinson and Danny McBride, there were already clips of Michael Cera, Rihanna and others making an appearance in Rogen's apocalyptic comedy. But there was one person whose appearance Rogen and the rest of his co-stars kept tightly under wraps — in more ways than one: Channing Tatum.

Tatum plays a small but hilarious role in the film, whose details we won't ruin. But when Rogen spoke to MTV News, he was more than happy to discuss it, offering some background on how it was created and then talking about Tatum's eagerness to throw himself into the role. Tatum especially liked the costume, which may come as a shock even to folks who pored over every frame of "Magic Mike."

MTV: Channing has an amazing cameo in the film.

Rogen: It's incredible.

MTV: Which you guys were really able to keep a great lid on.

Rogen: We did. It's pretty amazing. It's not really that out there yet.

MTV: So, how did that happen? How did you...

Rogen: We had this scene in the movie where we kick Danny out of the house and then we always thought it'd be funny if later when we leave we encounter him again and he's kind of like assembled this group of like cannibal misfits. Kind of like in "Mad Max" or something he's like large humongous now. And in the script he ...

Considering he's the first superhero ever created, creators Jerry Siegel and Joe Shuster only had history to draw from when they brought Superman to life in 1938. Every major styling choice we attribute to superheroes comes from Superman: capes, tights, iconic symbols, and — of course — underwear worn on the outside.

Superman proudly sported this iconic look for 75 years in numerous feature films and television series, defying trends in popular culture that saw other heroes change for more realistic and modern approaches. Superman's omnipresent underpants became as indestructible as his unbreakable skin.

Until came along.

Director Zack Snyder opened up about both the history of the red trunks and his decision to ditch them during an exclusive interview, part of "MTV First: Man of Steel." Snyder started by recounting the history of the hero's costume.

"When the costume was first invented in 1938, [Siegel and Shuster were] looking to find a superhero icon," explains Snyder. "The vision was turned toward Victorian strongmen, or circus strongmen. They wore their underwear on the outside of their pants because in the Victorian era, no skin could be shown. So when they first started doing circus strongmen, they would wear tights, and then they would put underwear over the top [of them] to give the illusion of nudity."

The fad that Superman started in 1938 continued with Batman, followed by heroes like Green Lantern, the X-Men, Robin, Thor, Martian Manhunter, Wolverine and countless others. But even though DC Comics rebooted the underpants off of Superman back in late 2011 with their New 52 initiative, Snyder ...
