Gossip

We told you a while ago that Selena Gomez and Demi Lovato were shifting from friends to frenemies because Selena replaced Demi with Taylor Swift as Bestie #1. Well, things are about to get even more...awkward. Demi's now showing off her latest arm candy -- Taylor's ex, Joe Jonas.

Access Hollywood's Billy Bush asked Demi, "So you [and Joe] went from boyfriend-girlfriend to best friends?" Demi told him it was the other way around, and when directly asked if she was dating Joe, Demi confessed, "Umm, yeah he is my best friend and he is incredible."

Even though Selena is dating Joe's younger bro Nick Jonas, don't expect paparazzi to catch these two Disney power couples on a double-date. After the romance news broke, Demi tweeted, "By the way... I would never lie to my fans. I love you all... and I've never been happier. :)" She may be smitten with Joe, but we bet she misses Selena.

Think about your room right now. Do you have posters on your wall? Framed photos of you and your friends on your desk? An childhood stuffed animal or old favorite sweatshirt laying around? Well, none of these things are in Kristen Stewart's trailer when she's on a movie set.

"I know actors who go on location and make their trailers their homes," Kristen says. "They literally put pictures up and stuff. I don't do that." Why? "I really like being where I am. And you're made to pretend that you actually live there, so it's like yeah, this is where I live now."

We get that a trailer isn't exactly a bedroom, but what's wrong with being surrounded by personal mementos? Apparently Kristen doesn't like the temporary-ness of it all. The 19-year-old Oscar presenter continues, "You start again at each place."

But we're actually not surprised by Kristen's easy-going attitude toward decorating...

After months of speculation, Robert Pattinson has confirmed that he's dating Kristen Stewart. And it's about time. According to The Sun, Rob spilled the beans at a post-BAFTA party on Sunday.

"It is extremely difficult, but we are together, yes," he said. "We can't arrive at the same time because of the fans. It goes crazy. This was supposed to be a public appearance as a couple but it's impossible. We are here together and it's a public event but it's not easy."

While it's great that Rob is finally fessing up to his relationship with Kristen, we're not surprised. At all. The pair have spent so much time trying to cover it up -- for instance, not walking the BAFTA red carpet together -- when it might have been easier to admit it from the get go.

Yes, fans do go "crazy" when they see the Twilight stars, but denying their relationship only feeds the frenzy. What if they appeared on the red carpet arm in arm? Would it have really been a big deal?

It takes a lot of star power to shut down the city of lights, but that's just what Justin Bieber is capable of. Thousands of teens showed up to an album signing for his latest single, 'Baby' at Paris's Citadium department store on Monday, which was eventually cancelled by Parisian police.

On his Twitter page, he told his followers in four tweets that, "PARIS IS CRAZY!!! Had some interviews this morning with mags and radio. got to practice my french a little. But then the instore... there were thousands of kids at the instore and the police were not expecting it. they reorganized the crowd and we got it going but... after a little while the police stopped it and came in and said it was over and i had to leave."

This isn't the first time Justin needed the police's help with crowd control. Back in November, cops forced Justin to send a tweet telling the out-of-control crowd that the event was canceled. Now Justin will have his turn to shut down New York City on April 10. That evening, he'll be the special musical guest on Saturday Night Live, following in the footsteps of other teen performers like Taylor Swift and The Jonas Brothers.

We have deets about a romance brewing on the set of Harry Potter and the Deathly Hallows. But we're not talking about a movie spoiler – this love is happening behind the scenes.

Jamie Campbell Bower and Bonnie Wright can officially update their Facebook profiles to say "In a relationship." Bonnie spilled the beans to Britain's OK! Magazine, "Yes, we're dating. We've been seeing each other for a few months, it's good. We're going to the BAFTAs together on Sunday."

Bonnie, who plays Ginny Weasley in the Harry Potter films, just celebrated her 19th birthday on February 17. What do you think Jamie gave her? Maybe an advanced copy of New Moon on DVD.

Jamie also plays wizard Gellert Grindelwald in both Harry Potter and the Deathly Hallows movies, which is likely how they met. But with Part 2 of the movie still filming and all the promotion they'll do over the next two years, this new couple will be spending lots of time together.

Does Demi Lovato have an admirer this Valentine's Day? She left this mysterious message on her Twitter page, "To whoever left me those valentines on my front porch, I love you! Best v-day gift ever received! :D"

Sounds like the work of Joe Jonas. They did just spend time in Walt Disney World together walking around Epcot, taking pictures with Mickey Mouse, and singing their duet "Make A Wave" at a private concert. Plus, after their quick vacation ended, Joe tweeted, "@ddlovato your awesome! I love u bff!"

But alas, Joe is not the cupid culprit...
