Now slimmed and toned Britney Spears took part in a spot of horseplay this weekend. She was a guest at a charity Polo match in Los Angeles.

She was accompanied by father Jamie at the event which had a team playing called the Spears Family.

It was sponsored by the Promises Foundation - a LA-based charity which helps Miriam's House, a home for recovering mothers and their children.
