Britney's Day in the Sun

While Britney's tear-filled interview with Matt Lauer may have been no day at the beach, her afternoon in Miami Thursday certainly was. More photos

Pregnant with her second child, the pop princess sported a bikini while frolicking in the ocean with hubby Kevin and son Sean Preston.

After putting to rest rumors that her marriage was in trouble on last night's "Dateline," the holiday seems to reinforce the fact that the Spears-Federlines are indeed a happy family. Even Sean Preston can't hide his contentment as mommy and daddy dote all over him.

We just hope everyone had their sunblock on.
