OutKast kicked off their anticipated reunion tour at Coachella this weekend, but the ATLiens weren't the only artists who created special moments at the California festival. Headlining sets from artists like Nas, Chance the Rapper and Pharrell saw plenty of cameos, including Jay Z, Beyonce, Drake and even Justin Bieber. See the most unexpected cameos from Coachella weekend one.

Jay Z And Diddy Joined Nas During His Illmatic Retrospective

Nas' iconic 1994 album Illmatic celebrates its 20th anniversary this year, so the Queens rapper brought out the big guns for his main stage performance on Saturday. He delivered the LP in its entirety, complete with a cameo from Jay Z, who performed "Dead Presidents" and "Where I'm From." Even Diddy dropped in to perform their collaboration "Hate Me Now."

Beyonce Did A Choreographed Dance With Solange

Why would Jay get to have all the fun? While her husband came out to mob with his one-rival, Nas, Beyonce showed up during her sister's set, and it was hard to tell which one of them had more fun on stage. Bey joined Solo for "Losing You," and although she's not featured on the song that didn't stop her from whipping it hard on stage. Big hair and huge smiles were in abundance.

Justin Bieber And Chance The Rapper Showed Off Their Best MJ Moves

Chance the Rapper's frenetic live shows are entertaining enough without cameos, but might as well do it big for Coachella, right? The Chicago rapper had one of the biggest surprises of the weekend, summoning ...

The MTV Movie Awards were bigger and badder than ever before this year, no small thanks to Conan O'Brien's stupendous turn as host. But his quips and fast-moving pace for the Awards weren't the only big moment of the night.

Here's every Movie Awards moment that mattered:

"The Fault In Our Stars" Exclusive Clip
Our first chance to see a scene from the eagerly anticipated "The Fault In Our Stars" would have been good enough, but to have it presented by stars Ansel Elgort and Shailene Woodley? Magic.

Puppy Pit
Seriously, there was a pit full of puppies dressed in movie costumes getting nuzzled by celebrities. How could that not be a moment that mattered? Heck, that might be the only moment that mattered.

Grumpy Cat Rocked The Carpet
You wouldn't normally think cats and carpets would go together, but Grumpy Cat was the hit of the red carpet, rocking Pharrell's hat and snapping cat selfies with everyone.

Conan's Epic Opener
He promised a record breaking 50 cameos, and Conan delivered — and then some, with the biggest awards show opening of all time.

Feeling Vine
Did we get awesome Vine versions of Movie Awards nominated movies? We sure did.

The "Lack" Of Musical Number
Promising there would be no musical number, Conan pulled out a guitar and welcomed guest Adam Devine on stage to sing about how they're not going to do a song. And then a gospel choir came out. Good thing they didn't sing a song!

Jared Leto Dedicates His Award
In a night filled with frivolity and ridiculousness, Jared Leto brought a ...

INDIO, California — Under a full moon, Sunday night at the Coachella Valley Music and Arts Festival was dominated by the powerful female, with heart-wrenching performances from Lana Del Rey and Little Dragon's Yukimi Nagano and surprise appearances from none other than Mary. J. Blige and Blondie herself, Debbie Harry.

The fellas, even Justin Bieber — taking the stage in the middle of the afternoon in support of Chance the Rapper with "Confident" — got in on the action, with Jhené Aiko presenting the festival's first appearance from Drake.

U.K. brothers Disclosure brought out Mary J. Blige for "F for You," and also featured Aluna Francis (of AlunaGeorge, who performed earlier in the night) on "White Noise," followed up by their smash "Latch," with an appearance by Sam Shepard.

Elsewhere, the dance scene was handled by Duck Sauce, Calvin Harris, Big Gigantic and Laurent Garnier, who killed it in the beautiful Yuma building.

Beck brought it down at over at the main stage, and Arcade Fire's theatrical Win Butler (always phenomenally backed by his wife, Régine Chassagne) wouldn't let the festival's official midnight curfew keep him from jumping into the audience after their perfect weekend-ending dance-up "Here Comes the Night Time" and "Wake Up" singalong.

Hard-rock fans would tell you if you didn't see legendary metal pioneers MotÖrhead, you missed the festival. Slash was onboard for "Ace of Spades" and more, and drummer Mikkey Dee pummeled the crowd.

Coachella kicked off Friday with the reunion of OutKast. Saturday's show included Lorde, alongside Pharrell, Nas, Skrillex, MGMT, Kid Cudi and Muse.

In a few months, Chris Pratt flies into the Marvel Cinematic Universe's cosmos as Star-Lord, the hero of

As Star-Lord, Pratt plays a human wandering the stars, stealing high-value artifacts and sleeping with as many alien women as he can. In other words, he's a bit of a jerk — a jerk that Pratt hopes to inhabit for years and years to come.

"I hope people really like it, and I hope I get to play that character for a very long time," Pratt told MTV's Josh Horowitz at the Movie Awards. "I think Marvel's been very smart about projecting into the future and what they're putting on their slate. It's based on what people like, so we'll put this movie out there and see how people react to it. Who knows?"

For now, the hard part's over. Pratt and the rest of his cast have completed production on "Guardians of the Galaxy," with director James Gunn and the Marvel team now working on polishing the finished product.

"They're cutting it together and loving everything that they see," said Pratt. "They're being very careful about what they release and very smart about getting people excited without giving away what the movie's about and not giving away the best jokes or story. I think people are very fired up to see it, and don't know what to expect."

"That's the best way to see a movie," he continued. "If I'm really excited to see something, and I have no idea what I'm about to see, I love that. I think that can be ...
