Since the Twitter phenomenon took off, we've all been following all of our favorite stars during their in every step of their lives! J-14 was the first teen magazine to start Twittering -- so now we're on Twitter Patrol to get to the bottom of the Fake Twitterers out there!

First up, Hannah Montana: The Movie's Lucas Till does NOT Twitter. We got the scoop straight from him just moments ago. "Actually no, that's an imposter," Lucas said. "I don't have a Twitter yet. Its so frustrating! My friends all the time are like, 'Hey you're coming to New York?' And I'm like, 'Yeahhhh...how did you know that?' I don't have a Facebook, MySpace, or Twitter. And they get really personal photos too sometimes! It's really weird."

Next, we talked to Sonny with a Chance and 17 Again star Sterling Knight last week and his too is a fake! "No, I do not have a Twitter," he tells J-14 exclusively. "No Twitter for Sterling."

But that doesn't mean they're all fake! There are some real celeb Twitterers out there.

Hannah Montana's Mitchel Musso's is real. "I just like that it can be the middle of the night and you can send out that text and get literally everyone texting you back," he tells J-14 exclusively. "They want to hear what you have to say. You can be as deep as you want. I remember I was with my buddy and we were on Twitter and he follows John Mayer, who sent out this massive text that just said, 'Can anyone tell me why I'm sitting in my bathtub with my guitar by myself?' or something like that. And all of these girls texted back."

The Suite Life on Deck star Debby Ryan is "obsessed" with Twitter too. "I got my friend Emma obsessed, too," she tells J-14 exclusively. "I told her, 'I want to keep you updated and you can keep me updated!' When I was going onto MySpace, I realized I was just going on to change my status and check my stuff and then leave. That's what I love about Twitter, you can look and in 10 seconds you can see, "Oh, Miley had a photo shoot. Demi can't wait to see Selena again." It's very cool because you can know people's plans and when people are free and when people aren't."

David Henrie of Wizards of Waverly Place is also an active (and real!) Tweeter. "It's fun to talk to fans and I can say funny stuff," he tells J-14. "It makes people's day sometimes!"
