Britney Spears Visits with Her Boys | Britney Spears
Britney Spears was reunited with her sons for three hours on Saturday.

After lawyers for Spears and Kevin Federline reached a visitation agreement Friday, the pop star saw her children Preston, 2, and Jayden, 1, for the first time since Jan. 3.

The boys left Federline's Tarzana house Saturday morning – put in their car seats by their father, according to photographers – and were driven by Federline's bodyguard to Spears's Studio City home.

A source involved in the case says, "The real hero was [Spears's father] Jamie. He has taken charge, and she has visitation again."

Sources confirm to PEOPLE that Jamie and Britney's psychiatrist were present for the visit.

After a three-hour stay, Spears's sons left again in the back of Federline's grey Dodge truck driven by his bodyguard.
