Jonathan "J.R" Rotem: Britney Spears' New Boy Toy

It looks like Britney Spears is out with a new man - and it turns out that he used to work for the family.

Britney has been stepping out, possibly wearing no pants, with Jonathan Rotem, who often goes by the nickname J.R. He's a big time music producer who's worked for the likes of Rihanna, Paris Hilton, and, yes, Kevin Federline.

As Perez Hilton notes, the pair were spied kissing in public on Sunday night, then went to a movie before heading back to Rotem's place.

The couple was supposedly getting cozy throughout Sunday evening, before Britney supposedly went home with J.R. Rotem at 3 a.m. and was not seen leaving.

Kevin Federline, of course, was an employee before he became Mr. Britney Spears. The irony is thick, very much unlike Nicole Richie.

Meanwhile, Paris Hilton has taken to - where else - MySpace to voice her support of her new BFF, and what she calls Brit's "partying ethics."

"For people to call out her parenting skills on behalf of her partying ethics is appalling. She goes home every night to [Jayden James and Sean Preston] and partying has not come in the way of her parenting."

Except, of course, when she spends the night at Paris' mansion. Or goes home with Jonathan Rotem. But really, who's counting.
