Britney Spears, no panties, no underwear, and now no boyfriend. The pop singer, who is working on her comeback album, has reportedly split from model boyfriend Isaac Cohen, just three weeks after the pair began dating.

It was Spears herself who revealed the fact, telling a pack of paparazzi who followed her Thursday night January 18th at a Coffee Bean and Tea Leaf cafe in Santa Monica, California, "Me and Isaac are not together, by the way." Being asked by photographers if the relationship was really over, she replied, "Yes."

Spears and Cohen were first seen together power-boating on Jan. 2 off the coast of Marina del Rey, California, and recently returned from a lavish weekend in Las Vegas. We'll see who's next on the queue to be Spears' new boy toy.
