The 3 singer reportedly ended her romance with Trawick at the end of February following a year-long romance because they had been arguingconstantly.

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, Trawick, 38, will still represent Spears 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 Trawick in January after learning he had been flirting with two women.

Spears, who has two sons with ex-husband Kevin Federline, and agent Trawick started dating in March 2009. They split briefly in August, but soon reconciled. - Bang
