'He's perfect,' Lovato says of 'Camp Rock' co-star and tourmate.By Jocelyn Vena Joe Jonas and Demi Lovato Photo: Kevin Mazur/VF1/WireImage After months of speculation, Demi Lovato is admitting that she's dating Joe Jonas, her old friend and onscreen love interest in two "Camp Rock" movies. In a new interview and on Twitter, the Disney star finally owned up to her relationship with the teen heartthrob. "He's actually my best friend," she said in a radio interview with Billy Bush, who then asked if they went from being a couple to being friends. "Um, no, kind of the opposite! "Yeah, he's my best friend and he's incredible," the "Sonny With a Chance" actress continued. "He's a complete gentleman; he takes me to the most amazing places. ... He's perfect! Lovato, who was recently seen with Jonas at the Vanity Fair Oscar party, said she's digging the glasses Joe has been wearing lately. "I think it's adorable and it totally suits him," she said. In the past, Jonas has been linked to Taylor Swift and Camilla Belle, while Lovato was said to be dating Trace Cyrus, Miley's brother. Jonas and Lovato recently recorded a song and music video together for the charity single, "Make a Wave," a part of Disney's 2010 Friends for Change: Project Green. "By the way... I would never lie to my fans," Lovato tweeted on Saturday, seemingly referring to news of her relationship status. "I love you all ... and I've never been happier." Last summer, when MTV News caught up with Lovato, she said she tries not to be bothered by gossip about herself. "I try not to listen to rumors," she said. "Rumors are stupid. They're not true. I mean, of course you get stuff like that all the time. You read it online, and you're just like, 'Why did they even make that up?' But, I mean, I don't really remember them, 'cause they're not important to me." Related Artists Demi Lovato Jonas Brothers

'I was a big moment for me,' she says of appearing in the sequel to the hit film.By Larry Carroll, with reporting by Sal Morgan Miley Cyrus Photo: MTV News Die-hard Miley Cyrus fans know that when it came time to shoot "Hannah Montana: The Movie," she eagerly stuffed the feature film with cameos by the likes of Tyra Banks, Taylor Swift and Rascall Flatts. Recently, the tables were turned on the superstar singer/actor, and when we caught up with her we had to ask about her scene in the upcoming "Sex and the City" sequel. "I've always been a huge fan of the show, I think they are so amazing," Miley said of the "Sex and the City" actresses, who stunned Hollywood in 2008 by making the difficult transfer from small screen to big while taking in nearly $60 million on its opening weekend. "It has such a great cast, and you can see the chemistry with all the girls." Although Miley had to be a bit tight-lipped about the details of her cameo, on-set photos seem to reveal that she and outspoken sexpot Samantha Jones (played by Kim Cattrall) show up at the red-carpet premiere of a movie wearing the same dress. "I was surprised [that they asked me]," Cyrus said of the scene. "It was a very glamorous day for me, to be on the carpet with the girls and share a really cool scene with Kim Cattrall — who I love. I think she's so great." "It was really, really fun and it was a big moment for me," Miley said of reaching that level of fame where people start asking you to make high-profile appearances as yourself. "It's one of those perks. You do so many things that aren't as much fun and are really the hard parts — but that was just one of those things where it was the day you got to play." Speaking of hard parts, Miley takes on what might be the toughest of her career with "The Last Song," her first non-"Hannah" starring role on the big screen, and an emotional drama to boot. The film is due in theaters March 31, roughly two months before Carrie Bradshaw and the "SATC" gang return to theaters. "I've always really been into the show, and they added a couple different cameos with all different types of people," Miley said of a cast of cameos that reportedly also includes Penelope Cruz, Liza Minnelli and Tim Gunn. "And they asked me to do one, which was a super big honor. "It was really easy and really fun," the 17-year-old star said of the cameo — but unfortunately, all she knows about the film is limited to her own scene. "I haven't seen any of it. All I did was my one tiny little part, where I just have to stand there. So I don't know [what the plot is]. "I'm excited, trust me," insisted the longtime "SATC" fan, saying that she's already making plans for a May 27 girl's night out with her friends. "I'll be waiting in front of the theater to go see it." Check out everything we've got on "Sex and the City 2."
