SEAN PRESTON AND JAYDEN JAMES FEDERLINE

As Britney Spears enjoys a Hawaiian holiday with her boyfriend Jason Trawick, her sons Sean Preston, 4, and Jayden James, 3, spent a fun-filled day at the beach in Los Angeles, California with their grandparents Jamie and Lynne (August 24).

Though Britney's parents split in 2002, they seemed to be getting along great as they played together with the boys and snapped a few family pics.
