Britney Spears posted a new promo for The X Factor on Twitter today, and we can't WAIT for the show to hit the small screen on September 12! Not only does Brit look amazing in the brief clip, but we also get to see her sassy side ... check out the video above!

In other Brit Brit news, it's being reported that the 30-year-old pop star may be doing a surprise appearance at the 2012 MTV Video Music Awards next weekend. We're guessing Brit's X Factor boss Simon Cowell is pushing for that!

Out with the old, in with the new!

Real Housewives of Orange County star Alexis Bellino debuted a dramatic new 'do on her Twitter account today, and we love her new look! The 35-year-old removed her hair extensions and cut her tresses into a short, blond bob, and is it just us or does she look years younger?!

"I wanted to do this cut for over a year!" she captioned the snapshot. "After last season nothing scares me! Thoughts?"

Co-star Gretchen Rossi, who showed off a shorter style similar to Bellino's last month, let her claws come out over the makeover.

"Funny when people copy a lot of things you do! Weird or compliment," she tweeted.

The back and forth insult trading continued over the microblogging site, with Bellino getting the last word when she laid claim to longer locks in the future.

"Let's just put this fire out now... I'm probably putting extensions back in 365 days from now and I'm not copying anyone. I'm calling it now. LOL," she snapped.

Meow ladies!

Justin Bieber has been hard at work in Hollywood on rehearsals for his upcoming Believe Tour, but that hasn't stopped the young heartthrob from showing love to his fans.

One of the girls even hands Biebs a Rubik's Cube. Talk about old school!

Good thing girlfriend Selena Gomez doesn't get jealous. Then again, Selena has plenty to be confident about.

Baby, baby, baby .... ooooohhh!

No Doubt has released their new single "Push and Shove." The catchy tune, with a ska vibe, debuted on Ryan Seacrest's radio program KIIS-FM.

When asked about the new sound, lead singer Gwen Stefani told Vulture magazine:

“But there’s no place like home; we’re so comfortable together, we understand each other. It feels, like, normal."

The new album Push and Shove hits stores on September 25.

Paging rumor patrol!

After pictures surfaced over the weekend of Rob Kardashian go-karting and clubbing with pop princess Rihanna, the Keeping Up with the Kardashians star chatted with Ryan Seacrest to dispel the romance speculation.

"It was just me and a bunch of girls [at the go-kart place]. It's because Rihanna's a friend, and she is friends with my friend Capricorn, and it was Cap's birthday. We all went out to celebrate our friend's birthday. It was fun. It was a good night," the 25-year-old explained to the radio host.

He might not be dating RiRi, but is he involved with fellow Roc Nation artist Rita Ora? It's anyone's best guess, but Kimmy K's little brother didn't exactly deny it.

Asked about the reports that the pair got matching temporary tattoos of each other's names, the ladies man played coy, revealing, "Rita is in the U.K. I'm just a fan. That's all. I'm a big fan. She does have tattoos."

This isn't the first time the USC grad and the British singer have been linked as a couple.

"It's not really a relationship. It's not that intense. He's a cool guy. We're close. We're good friends. I got his back and he's got mine," Ora dished to Complex magazine this past July.

We're a little disappointed Rob isn't dating the good girl gone bad!

After a family vacay in Sardinia to celebrate her father's birthday, Heidi Klum is back in the states with her 4 children, Leni, Henry, Johan and little Lou.

The 39-year-old Project Runway hostess may not be modeling for Victoria's Secret anymore, but she tweeted this pic from her trip just to remind us that she's still got it:



While Heidi's getaway was undoubtedly quite relaxing, there's a bit of drama waiting for her here in LA, as she's still feuding with ex-husband Seal. It turns out he used personal photos of their children in a series of Leica camera ads without Heidi's permission, and she's since hired a lawyer and demanded that the ads be removed from the company's website.

After the couple announced their divorce in January, Seal challenged Klum's request for primary physical custody of the children, asking instead that they both be given equal time with the kids, and he also reportedly contested her claim that there were no joint assets to be split between the two of them. (For the record, Seal has an estimated net worth of $15 million, while Klum is worth $70 million.)

We're sure this dress is for a red carpet event, but you can't help thinking that Kim Kardashian is just dying to walk down the aisle with beau Kanye West! After all, remember that song where he raps about putting her in a white dress?

The reality TV starlet tweeted this photo on Tuesday evening and wrote, "Late night fitting #pucci." Kim also got a spray tan and her eyebrows done, and we're not sure what this was for, but she certainly looks stunning!

Of course, that wasn't the only photo she tweeted -- she also posted this sexy shot and wrote, "Shooting a commercial under water today! Its a lot harder than it looks!"

If she wasn't an actress she could be a model!

Kate Hudson is overseas in Italy for the Venice Film Festival, and the blonde beauty looked laid back and lovely in jeans and a red tank as she arrived at the Hotel Excelsior to promote her latest film, The Reluctant Fundamentalist. The 33-year-old star gave birth to her second child a little over a year ago, but who would have known with that body?!

The Almost Famous star has been a busy bee lately! The A-list hottie is trying her hand at the small screen on the upcoming season of Glee. Miss Hudson plays dance teacher Cassandra July, and we can't wait to see her singing and dancing chops!
