Minnie Driver is one hot mama.

Currently vacationing in the Caribbean, The Riches actress, 42, showed off her sexy figure Monday, rocking a sporty, striped two-piece. By her side? Boyfriend Matt Felker, 31. (Britney Spears fans know Felker well–the model starred as the singer's bad-boy paramour in her "Toxic" video.)

During their beach trip, Driver and her beau played in the surf with her three-year-old son. Though the Barney's Version actress gave birth to Henry in 2008, she chose not to share his father's identity until this year.

In a February interview with The Observer, Driver revealed Henry's dad was a writer for The Riches, the FX show she starred in from 2007-2008.

Explaining why she finally decided to open up, the Oscar nominee said, "I don't need to protect him anymore. He can fend for himself." Added Driver, "We weren't together and he wasn't directly in the business…He's not famous, [so] there's no big story."
