But what many didn't realize is that Adam Sevani, MIley's LOL costar and rumored new love interest, was also at the show!

People have been saying that Miley and Adam have been flirting on the LOL set and that she dumped Liam Hemsworth for him. But in reality, they have been good friends for a long time (Remember, the Miley and her BFF Mandy Jiroux's M&M Cru dance battle again Adam's ACDC crew?). And on top of that, Adam was just in Step Up 3D which was directed by Jon Chu, who is also directing Justin's 3D movie, so Adam could have just been there to support his friends.

Do you think Miley and Adam are dating? Or just friends?

Justin Bieber is set to make his 3D big-screen debut next year, and he's already got his eyes on a new movie project!

The Biebs recently told a British newspaper that he would love to take on the iconic role of Danny Zucko (originally played by John Travolta) in a remake of the classic musical film Grease. "It would be a lot of fun," Justin says. "It's been talked about a lot over the years, but it would be awesome to play Danny." And Justin has the role of leading lady Sandy all picked out. "I would go for Miley Cyrus without hesitation," Justin says. "She can sing, dance and act."

There's no official word on if a Grease remake is underway, but it sounds like Justin would definitely sign on if given the chance!

Hey J-14ers,

It's been a while since we chatted with one of our fave groups, Varsity Fanclub, and a lot has changed since we last saw them! Singer Thomas Fiss left the band to pursue a solo career in 2009, so the remaining members -- Bobby Edner, David Lei Brandt of Evansville, Drew Ryan Scott, and Jayk Purdy were joined by singer/actor/dancer T.C. Carter. Their debut album is expected to drop this year, and they're currently touring Europe for the first time ever!

In the spring, they also released a new single called "Spank That," and they made up their own dance to go with the song! It's called "The Crab," and famous pals Miley Cyrus and Iyaz help show fans how to do the dance in a super fun video -- check it out here:

VFC has definitely not broken up -- they're going strong and ready to show fans what they've got when they return to the U.S. after their European tour ends this fall.

Are you excited to hear Varsity Fanclub's album?

<3,
J-14 Editors

The final season of Hannah Montana, Hannah Montana Forever, kicks off this today at 8 pm on Disney Channel. J-14 counted down the days and posted a new Q&A with one of its stars each day: Emily Osment, Moises Arias, and Jason Earles. Today is all about the star of the show, Miley Cyrus. Miley talked to us about how she has changed, the Hannah Montana wrap party, and whether or not she'd like to have a secret identity like her character!

J-14: Did you expect so much success from Hannah?
Miley: I think I knew it would be a success because the writers are so incredible and the script was amazing. But I don't think I expected it to be like the phenomenon that it is. I don't think I expected it to open so many doors for other artists on Disney to be able to involve music and acting and all that. I'm really proud to be a part of a really cool family. I'm excited to move on to new things. But I definitely didn't expect it to take off the way that it did, especially so soon. I can't believe it's already coming to an end, either. It feels like we just started.

J-14: How do you think you've changed since the first day you were on set?
Miley: I think I've definitely changed a lot. When I came to the set, I had my mom. She was my assistant, makeup artist, hair stylist, and wardrobe person all at the same time. My mom had me in this t-shirt that she had got for me that says "I should have my own TV show." I had it on with my skirt and full face make up. I was just sitting there like, "Oh my God, I'm on a Disney set. My life is like about to change." Sure enough, it did. I just remember coming to work with full face makeup, and now we're all in our pajamas when we come to work. I'm definitely a lot more comfortable with myself and I don't need to feel like I need to get dressed up every day. This is just like a home to us.
