Bristol Palin and Levi Johnston decided to split up

Many saw this coming. Bristol Palin, teen daughter of Alaska Gov. Sarah Palin and her fiancé Levi Johnston, father of their first baby has broken up. It was confirmed by People mag.

The split happened “a few weeks ago,” according to a source close to the couple, but it’s unclear what precipitated it. “It was a mutual thing,” adds the source.

“It kind of just happened,” says the source, referring to the split. “I thought they would stick it out. But I think they can work together to raise Tripp.”

“I’m not sure what caused [them to break up] – it’s common knowledge,” says another source who knows the family.

Rumor has it that the two are having problem even before the election and many feels that due to the Presidential election fever last year, the decision for this two to split up is being blocked.

Bristol gave birth to Tripp Easton Mitchell Johnston last December 27 of 2008 and currently she is finishing her high school.
