Britney Spears has re-hired her boyfriend to work as her agent.

The 'Hold It Against Me' singer and Jason Trawick - who have been dating since March 2009 - parted ways professionally last May but she has now re-signed with his company, William Morris Endeavor Entertainment, although he won't be the only person handling her career.

A source told website UsMagazine.com: "Jason will be part of the team handling her career. He won't be the only agent working with her, he will handling acting endeavours, but there will be a big music department also on her account."

It is thought Britney's family are behind the move as they know Jason has her best interests at heart.

The insider added: "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 recognise that."

Britney - who has two sons, Sean, five, and four-year-old Jayden, with ex-husband Kevin Federline - had originally stopped working with Jason so they could focus on being a couple.

A spokesperson for the pop star said at the time: "Britney and Jason have decided to end their professional relationship and focus on their personal relationship.

"Since wrapping her recent world tour, Spears has been busy in the studio working on her next album."
