Spears, 36, picked out a winner when she selected a bright blue bikini for her beach day on June 6.
Safety comes first for Spears, who made sure to wear a lifejacket while jetting around.
She also threw on some snazzy yellow tinted shades to protect her eyes.
As Radar has reported, Spears is locked in litigation with K-Fed, who is demanding more child support from the star for their two sons, Sean and Jayden.
In court documents obtained by Radar, Federline claims he and the boys live in near poverty in a tiny rental home.
Federline, 40, also claims he only banks $3,000 a month as a backup dancer and DJ.
