Britney Spears is proving she has put her bitter custody battle with ex-husband Kevin Federline behind her by enjoying a fun-filled Mexican vacation.

The Toxic star appeared to be enjoying herself as she sunbathed with pals on a beach in Mexico, and even sparked rumors of a budding romance after dancing intimately with a mystery man. Spears and the unnamed male laughed and joked as they mock ballroom-danced around the pool - with the singer showing off her newly toned and tanned body as the man put her through her moves.

An onlooker tells Britain's Daily Mirror newspaper, "Britney looked great in her bikini. She was having a whale of a time with this bloke (man), they seemed close."

The trip comes just days after Spears agreed to a custody settlement with Federline. Federline retains full custody of their young sons Sean Preston and Jayden James, while she will pay him $20,000 -a-month in child support.
