Jonathan Rotem

The last time we heard from the classy J.R. Rotem, he was producing Hayden Panettiere's new album and talking about how last winter, he railed Britney Spears wheelbarrow style. A true gentleman kisses and tells to Blender.

But apparently the greasy producer's bragging hasn't damaged relations between the pair, as Britney Spears was spotted all over town with J.R. Rotem yesterday!

Quote-unquote music producer J.R. Rotem apparently enjoyed massive amounts of sex with Britney Spears somehow.

And he's not afraid to disclose his specific, kinky sexual position of choice when he was doing the pop princess, either.

And the Hollywood Gossip world turns. Another day, another Britney Spears romance.

Well, this one is old. And we've talked about it at length already.

It looks like J.R. Rotem is at it again.

The quote-unquote music producer, best known as Britney Spears' first fling since ridding herself of FedEx, is on the prowl again.

Looks like everyone's kicking J.R. Rotem to the curb and moving on to bigger and better things.

One look at the dude makes it easy to see why.

The 15 minutes of fame may be ticking away for J.R. Rotem, but he's doing the best to make the most of every second.

First he was seen smooching Britney Spears, leading many to believe there could be a relationship brewing there. Alas, that appears to have been a one-shot deal - but J.R., whose real name is Jonathan, didn't let that stop him from chasing some underage tail.

The wristwatch of J.R. Rotem probably reads around 14:56 right now.

That's right, with the clock already running out on his 15 minutes of fame, Britney Spears' recent boy-toy is making a last-ditch effort to stay in the spotlight ... by clubbing like a madman and getting busy with Bai Ling.

Is J.R. Rotem already over Britney Spears?

Ever since photographers caught the sleazy music producer locking lips with the soon-to-be-ex-Mrs. Kevin Federline, he hasn't been seen anywhere near her.

Yesterday, Kevin Federline fans noted that Britney's new man, producer J.R. Rotem, had been removed from Kevin Federline's Top 20 MySpace friends list.

And we know what you're thinking: Come on, Kevin Federline doesn't have any fans.

Sigh. Guess tapping the back side of Britney Spears just doesn't get one as far as it did back in the good ol' days.

Maybe it's the fact that millions were given an unsolicited crotch shot by Britney last month and the allure is kind of lost.

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.
