Report: Isaac Cohen Dumps Britney Over Phone

Look out, dudes: Britney Spears is single again.

That's what TMZ is reporting today, after her newest boyfriend, Mr. Isaac Cohen, dumped her over the phone - saying she's "a bit much" for his taste!

Britney got the bad news Sunday night while she was in New York and Isaac was in L.A. The pair had been together since mid-December, and Isaac was Britney's first boy (we refuse to count J.R. Rotem) since she split from the great Kevin Federline on November 7.

According to a friend, Isaac has been "looking to get out" for some time, because it was "a bit much for him ... it was too much of a whirlwind."

For some time? Bear in mind that we first reported that Britney and Isaac were dating on January 10. She must be a real nightmare!

We can only assume that Isaac will now resume his anonymous life, being Jewish and working on his career, while Britney continues to drink beer and pine for Justin.

Think we're kidding? TMZ reports that Brit was partying last night with JC Chasez - Timberlake's former boy band-mate - in NYC, and freaked out when the DJ at the club dared play on a Justin Timberlake track.

We're guessing the song in question wasn't "Dick in a Box" featuring Andy Samberg. But by the look on her face, Britney was none too pleased.

According to our sources, Britney Spears exchanged a few words with the DJ, and the song was promptly replaced with something more to her liking.

Spears doesn't need to worry about the same thing happening with any of K-Fed's music. Although the rap in his Super Bowl commercial was pretty damn catchy!
