Music producer JONATHAN 'JR' ROTEM insists he is not a Hollywood party boy, even though he was recently photographed kissing Britney Spears and has been out on the town ever since. Rotem has been working with the Spears on her upcoming album and the two were photographed in Los Angeles kissing and cuddling on 10 December (06). Since their date he has also recently been spotted with 17-year-old HEROES star Hayden Panettiere and Chinese actress Bai Ling. The 31-year-old slams reports that he is a regular on the party scene and insists he is too busy working. Rotem is currently working on tracks for Jennifer Lopez, JoJo, Mya and Jesse Mccartney and claims he doesn't have time for a social life. He tells MTV News, "Within a 24-hour time period I was in with 50 (CENT), then Britney." Rotem has also worked with The Game, Rick Ross and Dr Dre. He adds, "Whoever I'm in the studio with, I try to bring the best out of them and let them bring the best out of me. I just try to make the best possible song."
