Britney Spears' days of mixing business and pleasure are over: She and her agent-boyfriend Jason Trawick have called it quits – professionally.

"Britney Spears and her long time agent, Jason Trawick, have decided to end their professional relationship and focus on their personal relationship," her rep tells "Since wrapping her recent world tour, Spears has been busy in the studio working on her next album.”

Despite split rumors earlier this year, the two are still going strong since they began dating last summer.

This past weekend, he joined the singer, 28, and her two sons, Sean, 4, and Jayden, 3, for a trip to Disneyland.

"They had the best time," a source tells Us. "It was a really special time for all of them. Britney was glowing. The kids love Jason, so they had a really fabulous time."
