Minnie Driver isn't shy about showing off her hot new romance.

Wearing a skimpy white bikini, the fabulously fit 41-year-old shared a sexy smooch with her model beau Matt Felker at Paradise Cove in Malibu, Calif. Sunday. The blonde hunk couldn't keep his hands off the Barney's Version actress, as he was seen caressing Driver's bottom during the passionate embrace.

If Felker looks familiar, it might be because the 31-year-old appeared in Britney Spears' "Toxic" music video in 2004. (He's also appeared in the TV movies Flashpoint and Dirty Famous.)

Prior to her relationship with Felker, Driver -- who has never confirmed the father of son Henry, 2, -- dated several of Hollywood's hottest men, including Matt Damon, Josh Brolin, Harrison Ford, John Cusack and Foo Fighters' Taylor Hawkins.
