Britney Is Single Again

OK! Magazine is reporting that Britney Spears and new boyfriend ? K Fed lookalike Isaac Cohen have broken up.
Model Cohen?s agent at L.A. Models confirmed to OK! ?They are no longer an item.?

A friend of Isaac is quoted as saying he has been "looking to get out of the relationship for a while. It was a bit much for him. There was a lot of drama - it was too much of a whirlwind. It wasn't one thing in particular. He likes her. They had a good time together. He was doing his best to help her out - but there is only so much one person can do."

However Ms Spears doesn?t seem to be sitting at home mourning the end of the relationship (or looking after her kids), Spears and her entourage were spotted last night New York nightclub Marquee

"She kept making a lot of trips to the bathroom," says one spy witness. We're saying nothing...
