Britney Spears has been spotted frolicking with a mystery man on a holiday in Mexico. Could this new acquaintance be husband number three?

The reformed pop wreck laughed and joked as she sunned herself with friends on a beach in Mexico, and sparked rumours of a budding romance after dancing intimately with a dark-haired hottie.

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 the Daily Mirror: "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 her ex-husband. K-Fed retains full custody of their young sons Sean Preston and Jayden James, while she will pay him $20,000 (£10,000)-a-month in child support.
