Chris Brown hit the red carpet at the 2012 American Music Awards at the Nokia Theatre L.A. Live on Sunday evening, and this leather ensemble is actually a pretty tame outfit -- for him, anyway!

The 23-year-old R&B superstar is nominated for Favorite Soul/R&B Male Artist and Favorite Soul/R&B Album for Fortune, and he's going to perform “Everyday Birthday” with Swizz Beatz and Ludacris during the broadcast. Can't wait to see what he has in store!

Hayden Panettiere may not be winning an American Music Award tonight (she's presenting), but the 23-year-old actress has won us over with her fab figure and stunning sequined dress! And those matching satin peep toes? To die for!

But maybe next year she could be walking away with some hardware from the AMAs? After all, that's actually her singing on Nashville, and if you ask us, she's pretty good at it! Then again, we looooove the show, so we are a little biased!

We're not sure what's more over the top -- Christina Aguilera's spray tan or Nicki Minaj's hair!

We'll give Xtina a hand for lopping off the pink tips and going for a sleek bob, but how about this purple Pamela Roland dress? It doesn't really do wonders for her body, and the orange hue of her skin isn't the best match for the lavender frock. But again, bonus points for the hair...

On the other hand, Nicki killed it with her look, even if it is a bit on the neon side. Come on, would you really expect her to go for a subtle LBD? This girl is all about flashing her brights! And it must be her lucky dress, because she just won her first award of the evening, for Favorite Rap/Hip-Hop Album for Pink Friday: Roman Reloaded. Congrats!

Justin Bieber and Selena Gomez are far from breaking up ... the teen heartthrobs spent the night together AGAIN last night, after a quiet night in on Friday, the two pop stars hit the recording studio Saturday night to get some work done.

Some other famous voices joined Selena in the studio ... but we'll tell you more about that later ...

Bieber joined Gomez at Conway Studios around 10pm and they stayed until midnight before leaving in Justin's van, back to the Four Seasons Hotel, where he's been staying (when he's not sleeping over at Selena's house).

We got a single snap of Selena as she made her way into the hotel, but Bieber was playing hard to get :)

It's a tween dream! Miley Cyrus and Taylor Swift joined Selena Gomez at Conway Studios yesterday, for what appears to be a top-secret project ...

The American Music Awards are tonight -- maybe they're doing a quickie track for the show?

Miley joined Selena at the recording studio around 2pm Saturday and stayed for about two hours. Then Taylor arrived around 7pm and she and Selena left for dinner at Osteria La Buca in West Hollywood. After, they both went back to the studio and Taylor stayed for another hour.

We all know what happened next ... Justin Bieber arrived to join his girlfriend before heading back to his hotel together to spend their second night in a row together!

So just WHAT are Miley, Taylor and Selena cooking up?

Pink and her one-and-a-half-year-old daughter Willow went for a 7am coffee run on Sunday in Venice, and both of the girls looked a bit sleepy!

A few hours later Pink tweeted the photo below and wrote, "#AMAs !!!!! Thanks guys but a little early for mama."



Be sure to stay tuned to our coverage of the 2012 American Music Awards tonight!

She may be single, but she sure is living it up!

Eva Longoria celebrated a friend's birthday at the Garza Blanca Resort in Puerto Vallarta, Mexico, and the 37-year-old actress had a blast during her stay! Eva tweeted, "Didn’t want to leave tropical paradise of @garzablancapvr! Could have sat by the infinity pool overlooking the ocean 4ever. Pure bliss!"

Now that she's back home, she's set to begin work on Married and Cheating, a romantic comedy "centered on three different couples with one thing in common: infidelity." Then maybe she'll dip back into the dating pool?

Hopefully Ashton Kutcher isn't jealous about his lady love spending all this time with her Oz: The Great and Powerful co-star!

On Sunday Mila Kunis, James Franco and Paul Haggis were snapped strolling the streets of Rome, and later we spotted the brunette beauty flossing her teeth ... in the middle of the sidewalk! Hey, it's probably better than her walking around with a piece of spinach stuck in her chompers...

Oh, and Ashton probably doesn't need to worry about James romancing Mila, as he later stepped out with Matthew Modine's 22-year-old daughter Ruby:



But what about those Ashley Benson rumors?
