I forgot about them. The couple had been laying low since Chelsea was hitting the fashion show circuit last year.

“They are no longer together,” a source close to Clinton confirmed. Clinton and Klaus, both 25, had dated since 2002, after they met at Oxford University. But rumors about their relationship troubles have abounded since January, when Klaus, an American-born Rhodes scholar, left for Iraq.

In the past year, Chelsea has been linked to her childhood friend Marc Mezvinsky, a Goldman Sachs employee who is the son of former Iowa Congressman Ed Mezvinsky and former Pennsylvania Congresswoman Marjorie Margolies-Mezvinksy.

Chelsea was also seen regularly with twentysomething Bumble Bee tuna heir Evan “Bumblebee Boy” Metropoulos, making the nightclub rounds. Her reps called both men “just friends.”

In March, Clinton made the gossip pages when she had to be helped by bouncers out of the Marquee nightclub. She was attending a boozy birthday bash where “friends” said she was drowning her sorrows about the state of affairs with Klaus.

The Bumble Bee tuna heir reference made me giggle. She’s a catch. The powerful are ready to pounce.
