Justin Bieber makes his acting debut on Nickelodeon's True Jackson, VP tomorrow, but we've got two clips from the season two premiere for you to watch now!

The 15-year-old pop star performs his smash single, 'One Time,' and saves True's almost-doomed fundraiser by coming through as its musical act.

In our exclusive interview with the Canadian singer, Justin says working with Keke Palmer -- and the entire experience as a whole -- was "a lot of fun"

"The set was just great," he told JSYK. "There were a lot of cool people and just being able to act and stuff was a lot of fun. I'm looking forward to seeing [the episode]. I haven't actually got to see it yet."

As for Justin's plans to do more on-camera work, he says it's a definite possibility. "Yeah, I think I will act more in the future. I don't have a lot of experience, but I'm getting better and better at it."

Justin's episode of True Jackson, VP airs on Saturday, November 4 at 8:30 p.m.

Demi Lovato is rocking hard in her new Got Milk? ad!

The 17-year-old singer and Disney star is crowd surfing in her print advertisement, with the caption: "On stage I get my energy from my fans. Off stage I dive into a glass of lowfat milk. The protein and other nutrients give me rocking. Here we go again!"

Nice album title reference!

Demi also says, "I love drinking milk because it keeps me lean and strong. Not only that, it keeps my hair and nails healthy."

What do you think of Demi's milk ads?

Check out some behind-the-scenes footage from her photoshoot here, and take a look at Demi's new video, 'Remember December,' here.

Just like the lyrics in Care Bears on Fire's song 'Everybody Else,' the girls of the pop-punk trio "don't want to be like everybody else." When it comes to fashion, Jena, Sophie and Izzy have their own unique style and are here to show you all of their favorite pieces in this brand-new webisode.

Jena loves shoes, particularly Converse and Doc Martens, which she's managed to customize in her very own way. Sophie adores tights in every color and pattern, while Izzy lives for the look of tutus and one-of-a-kind hats. Take a peek inside Care Bears on Fire's wardrobe below.

An end-of-the-world movie releasing on Friday the 13th? That's creepy.

2012 looks like it's going to be a huge hit at the box office. The ultimate disaster flick was written by the same guy who wrote Independence Day and The Day After Tomorrow.

The movie, starring John Cusack, Amanda Peet and 9-year-old Morgan Lily, is about an ancient prophecy from the Mayan calendar, predicts that the world will come to an end on December 21, 2012. Chaos ensues and crazy explosions, suspense-filled crashes and heart-stopping catastrophe take over the screen. Will this be the end of the human race? Or can it be stopped?

Watch the trailer for the movie below, and take a look at Adam Lambert's video for 'Time For Miracles,' which is featured in the film.

Demi Lovato used her Twitter account to show fans her new video, 'Remember December, today. The 17-year-old Disney star tweeted, "Have you seen my new music video Remember December??? Let me know what you think!"

"The music video relates to the song in a way that a girl has so much to say to the guy, and it feels like he's not listening, and she wants him to remember everything that they had," she told MTV News. "And so instead of having a love interest in this video, it's all about being fierce and kind of, like, taking control as a girl. It's like girl empowerment. Yeah, divas!"

You can watch 'Remember December' here. Demi's new album, 'Here We Go Again,' is in stores now.

It looks like Twilight did a great job of laying the foundation for New Moon. According to Fandango, the vampire sequel has surpassed its predecessor in advance ticket sales on the popular movie site.

New Moon is now Fandango's No. 4 Top Advance Ticket-Seller on Fandango, currently representing 75 percent of the entire site's ticket sales. Twilight comes in right behind New Moon at No. 5.

"Ever since we started selling advance tickets to New Moon on August 31, the demand has been unstoppable, as the fan base just keeps growing every day," says Fandango Chief Operating Officer Rick Butler. "New Moon is tracking to be Fandango's No. 1 top advance ticket-seller of all time."

Wow! But are you really that surprised?
