While Mommy’s away, the boys will play! Britney Spears‘ sons Sean Preston and Jayden James enjoyed a day at the beach at home in L.A. with grandpa Jamie Spears and grandma Lynne Spears while Brit enjoys the Hawaiian sun with new guy Jason Trawick. The two adorable blondes ran around playing together and built a sandcastle. And Jamie and Lynne seemed to be playing nice too (the two have been divorced since 2002).
