Fun, sun and marriage done?

Could Kevin Federline be taking the pleas for privacy that wife Britney Spears begged for during her Dateline interview literally? MSNBC’s The Scoop claims that despite being photographed together on a Florida beach, frolicking in the sand and surf with son Sean Preston, the couple spent the majority of their recent vacation apart, even going as far as staying in separate rented houses.

"She did it to get away from Kevin," a source told In Touch Weekly regarding the lodging arrangements. Britney was also (wisely) a no-show at Kevin’s scheduled appearance at South Beach’s Club Mansion, where he stayed until 3:30 am downing Cristal champagne with eight of his own Feder-friends (he apparently missed the Jay Z memo about how Cristal no longer has street cred).

Despite the extra effort and energy, though, that it must require, Britney is taking precautions to be sure her marriage looks magical from the outside. A supposed friend divulges that, regarding her relationship with K-Fed, the Britster "wants the world to think they’re happier than ever." Or, at the very least, In the Zone.
