Britney Spears cooled off this weekend from the scorching Vegas heat by taking a dip in the Palms hotel pool. She kept her bikini body mostly covered up while vacationing with her dad Jamie. Afterwards, Britney got dressed for a shopping trip at Caesar's Palace before a father-daughter night at the Cinevegas party. While Brit was behaving herself, elsewhere on the strip Kevin Federline accepted his Father of the Year award at Prive. Kevin may have made it home in time to spend Father’s Day with their boys (and his other children) but if anyone deserves recognition in this family it’s Jamie Spears who has helped Britney do a 180 in a matter of months.
