"Jason will be part of the team handling her career. He won’t be the only agent working with her, he will handling acting endeavors, but there will be a big music department also on her account," a source tells the mag.

The pop star has enjoyed several recent holidays with her 39-year-old William Morris Endeavor Entertainment agent, and despite Brit dropping his representation last year, they've remained romantically involved.

As for why they're back on professionally, the source adds, "Jason is someone the family trusts, they know he will make the best decisions for her and she feels comfortable with him. WME is absolutely the best choice for Britney. They are the best at what they do and her team recognize that."

Britney and Jason have been dating for two years.
