Justin Bieber and Selena Gomez spent the night together, first on Friday, and then on Saturday, and before going to the American Music Awards on Sunday, we spotted the two young stars at the Four Seasons Hotel in Beverly Hills.

Justin was greeting a throng of fangirls outside of the lobby, and Selena was snapped driving off in her white SUV, wearing the same clothes from the night before!



Too bad he didn't bring her as his date to the AMAs...

Jessica Simpson posed for photos at an event for her Jessica Simpson Collection in Tampa, Florida on Saturday, and the 32-year-old singer/actress/Weight Watchers spokesperson looks like she's lost all the weight she gained during her pregnancy with baby Maxwell!

Well, almost all of it -- last month Simpson revealed that she was within ten pounds of her goal weight. "I feel positive about how I've done so far and really good about the goals I have set," Jess told Us Weekly. "Most people can tell a difference every time they see me, which lets me know I'm making progress."

She sure is! But won't the real test be how she looks in a pair of daisy dukes?

Justin Bieber swept the 2012 American Music Awards tonight, taking top categories Artist of the Year, Best Pop/Rock Male Artist and Best Pop/Rock Album.

Katy Perry was his female counterpart in the Pop/Rock category, while maroon 5 won for best Pop/Rock group.

Everyone's favorite scorned lover, Taylor Swift, took the prize for Best Country Female Artist, while Luke Bryan took the male award.

Nicki Minaj was the only artist besides Beiber to win more than one award -- she took Best Rap/Hip-Hop Aritst and Best Rap/Hip-Hop Album for Pink Friday: Roman Reloaded.

Beyonce and Usher won the prizes for Best Soul/R&B Artists and Rihanna won Best Soul/R&B Album for Talk That Talk.

Wow! Either she's making a point to show Jake, Conor, Taylor, John and company what they're missing out on, or ... she's trying to wow One Direction hottie Harry Styles even more?

Taylor Swift worked the red carpet at the American Music Awards on Sunday night in a Zuhair Murad dress and Jimmy Choos, and she even gave us a sultry over the shoulder shot. Hot!

Taylor performed “I Knew You Were Trouble” during the show, which is reportedly about ex-boyfriend John Mayer. The 22-year-old singer is nominated for Favorite Country Female Artist, and she's up against Miranda Lambert and Carrie Underwood. Think she'll win?!

Harem pants, red studded loafers and a shiny tank top aren't what most guys would wear, but most guys aren't Justin Bieber!

The 18-year-old pop phenom posed for a few solo photos at the 2012 American Music Awards tonight, but he did bring a plus one -- his mom Pattie! Sure, he may be having sleepovers with on again/off again girlfriend Selena Gomez, but it doesn't look like they're ready to make any red carpet appearances just yet...

Justin just nabbed the award for Favorite Pop/Rock Male Artist, and he's also nominated for Artist of the Year and Favorite Pop/Rock Album for Believe ... think he'll win all three?!

Ke$ha posed for photos on the red carpet at the 2012 American Music Awards at the Nokia Theatre L.A. Live on Sunday night, and she's not our pick for best dressed, but she does win the most improved award!

The 25-year-old singer will perform her latest single “Die Young”, and after tonight's show, she'll be busy promoting her new album, Warrior, which hits stores on December 4.

Of her new music, K Money recently told Vibe magazine, “The first record was a celebration of partying and being young, but this record’s a better look at my personality. Whatever, I drink like a champion. But I can also do other stuff. I have a sense of humor about my lyrics. I’m not a train wreck, I’m just having fun.”

Awww, looks like they're ready for prom! Well, a sophisticated 30-plus prom!

“Getting ready for #amas almost done, need to find hubby and my clothes,” Pink tweeted before the show. “Found the clothes, now where’s that @hartluck?” Ha!

The 33-year-old singer will perform her song “Try” during the show ... you KNOW there's gonna be a wardrobe change, so we can't wait to see what Willow's mama slips into for her set!

But is it just us, or did Gwen Stefani TOTALLY pick out bandmate Adrian Young's outfit? It looks like something straight off the L.A.M.B. runway!

No Doubt hit the red carpet at the 2012 American Music Awards in Los Angeles on Sunday night, and while they're not nominated for any awards this year, the group are set to take the stage later this evening. Push and Shove just came out in late September, so even though they missed the mark for the AMAs, we're guessing they've got their eyes on Grammy gold. Those nominations will be announced on December 5.

Can't wait for their back-to-back shows at the Gibson Amphitheater in LA, which kick off next week. Will you be going?
