The two "have decided to end their professional relationship and focus on their personal relationship," a Spears rep told People magazine. "Since wrapping her recent world tour, Spears has been busy in the studio working on her next album."
The pair began dating last summer and have dodged engagement rumors for months. "They are very happy," a source said of the couple. "Things are really good with them."
The 28-year-old Spears might be taking it slow after two failed marriages. She married Jason Alexander, a childhood pal from Mississippi, in an ill-conceived Las vegas ceremony back in 2004 and then split three days later. Eight months after that, she got hitched to Kevin Federline, one her dancers. That marriage lasted jjust over two years and produced two children.
Trawick, 38, works for the William Morris Agency. Losing Spears as a client will still leave him with some high-profile celebs to represent, including Taylor Swift, Hilary Duff and Paris Hilton.
