Britney Spears has split from her boyfriend Jason Trawick.

The '3' singer reportedly ended her romance with the talent agent at the end of February following a year-long romance because they had been arguing constantly.

A source said: "They were fighting a lot and have not been getting along. They both just needed to take a break from each other. It wasn't working out."

Despite their split, Jason, 38, will still represent Britney through the New York-based entertainment agency, William Morris Endeavor Entertainment, where he works.

This isn't the first time the pair have seemingly split.

The 28-year-old pop beauty dumped Jason in January after learning he had been flirting with two women at Los Angeles' Roger Room bar before getting back together.

Britney - who has two sons with ex-husband KEVIN FEDERLINE - and agent Jason started dating in March 2009. They split briefly in August, but soon reconciled.

Since their romance began, Jason has proposed to Britney several times.
