Britney Spear's agent boyfriend Jason Trawick has left the talent agency that represents her.

The 39-year-old is said to have wanted to change his working hours so he could spend more time with Britney and her two sons, Sean Preston, five, and Jayden James, four.

Jason has been a longstanding staff member of William Morris Endeavor, a company which also represents country singer Taylor Swift.

"Since meeting Britney, his priorities have shifted and he would much rather be home at night with her and her boys," a source close to Trawick told American publication People. 't was the only company he worked for since arriving in L.A. He has been approached by different firms over the years, but nothing ever made him make the leap until now."

Jason will be joining American agency Famos to oversee a new creative partnership between musician and media impresario, Dave Stewart and legendary Rolling Stones' frontman, Mick Jagger. Titled f**kstar, the project is described as an arts and entertainment brand.

Britney's beau, who has been dating the pop star since 2009, described his move as "a very exciting opportunity for me professionally," and says he's "humbled to be a part of such a visionary partnership."
