Has Britney's Make-Out Partner Moved On?

Arizona clubgoers recently saw Spears getting hot and heavy with football stud Matt Leinart. Now, TMZ cameras have spotted record producer "J.R." Rotem, linked with Britney a few weeks ago, leaving a party at Paris Hilton's Hollywood Hills home with sultry R & B singer Mýa this weekend. Rotem made sure to open the car door for her. Such a gentleman!

Also at Paris' place: Cuba Gooding, Jr., sister Nicky Hilton, buddy Brandon "Firecough" Davis, Chris Judd and Kim Kardashian, who just loves the beaches in Australia this time of year.

Teddy's at the Hollywood Roosevelt Hotel saw the likes of Travis Barker, Tom Green and Taryn Manning, while Rachel Hunter, Carlos Mencia and Dane Cook had lots of laughs for TMZ cameras outside of Hyde.
