Federline joins Spears for family barbeque

Britney Spears and ex-husband Kevin Federline have started the new year cordially for the sake of their two sons - after the former backing dancer joined the 'Toxic' star at a recent family barbecue.

The 30-year-old, who shares sons Sean Preston, three, and Jayden James, two, with Spears, accepted an invitation to join the feast on Sunday, reports People.com.

Federline reportedly arrived at Spears' new Hollywood Hills home at noon to pick up the boys from their weekend visitation.

But after the singer's dad, Jamie, extended a hand to his ex son-in-law, Federline reportedly enjoyed the day with the Spears family, and reportedly returned home with the boys five hours later.

Federline was awarded custody of the children in 2007, a year after splitting from Spears.

The pop star officially handed legal and permanent conservatorship of her estate over to her father earlier this month - almost a year after he was first put in charge of his daughter's affairs following a series of public meltdowns.
