Lynne, Jamie, Preston & JJ Hit the beach too!

While Spears's sons Preston, 4, and Jayden, 3, stayed in L.A. with grandparents Jamie and Lynne, the boys did get some surf and sand fun of their own in Santa Barbara. 

"Preston and Jayden had a blast on the beach. Jamie and Lynne seemed to very much enjoy spending time with the boys, and together they built sand castles and played tag," says an onlooker. "The boys looked so cute and were beyond excited about the beach. Jamie and Lynne looked very happy together as well." 

Adds a source, "Britney told Preston and Jayden that she was going to the beach and promised the boys that they would get to go also. The boys had the best time in Santa Barbara with their grandparents."
