Spears and Federline’s trip to Aqua Island cost them $250,000. The reason for the hefty price tag? In Touch’s source claims Britney and Kevin had separate houses so that they wouldn’t have to spend their vacation together. “She did it to get away from Kevin,�? Britney’s “friend�? said.

Another confidant of Spears says the popstar “wants the world to think [she and Kevin are] happier than ever.�? Unfortunately, though, the couple is having trouble keeping up appearances. While in nearby Miami for a promotional event, Federline was up to his old tricks. He stayed out until 3:30 am with eight buds (and no Britney). The guys danced and downed Cristal. Kevin’s club-going behavior is said to be one of the couple’s sore spots.
