She’s got a NEW man in her life – and her OLD body back!

Smokin’ hot mama Britney Spears soaked up the California sun in a bikini Monday in Malibu, and Breaking Celebrity News has the sexy shots.

The 31-year-old former The X Factor judge -- who in January split from her fiancé Jason Trawick -- tied her bikini top down to avoid tan lines. She also (wisely) was spotted repeatedly pulling up her swimsuit to avoid a possible wardrobe malfunction.
