J.R. Rotem Spotted at Hot Paris Hilton Party

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.

Cameras spotted Rotem leaving a hot party at Paris Hilton's Hollywood Hills home with once-hot R & B singer Mýa this weekend. Rotem even made sure to open the car door for her. He really is a gentleman - something we remember from the good old days when he and Britney were seen together!

Also at Paris' place that night: Cuba Gooding, Jr., sister Nicky Hilton, buddy Brandon Davis a.k.a. Greasy Bear, Cris Judd and Kim Kardashian.

Wow. Inviting J.R. Rotem and not her former BFF, Britney? Ouch, Paris. That hurts. And who invites Cris Judd to anything?

Rotem, who has enough oil in his hair to join OPEC, has also been spotted with cuties such as Bai Ling and Hayden Panettiere since bidding farewell to Brit.

As for Britney, she doesn't appear to be losing much sleep over breaking things off with J.R. (really, though, who would), and was most recently spotted hooking up with Arizona Cardinals quarterback Matt Leinart at a club.

That guy gets around, and we're not talking about the pocket.
