It's official: she and Isaac have gone their separate ways...
Britney Spears is single again after splitting with Kevin Federline lookalike, Isaac Cohen.
The pair began dating in January but Isaac's LA Models agent Brandi Lord, confirmed, "They are no longer an item."
And according to US reports it was Isaac that extended the elbow.
One insider told Perezhilton.com, "(Isaac had 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."
Meanwhile, it doesn't seem Britters is too heartbroken by the break-up - revellers at New York nightclub Marquee spotted her reportedly having "a whale of a time" with her mates last night (February 6).
