Josh Duhamel wears a heart thong on 'Ellen,' talks Valentine's Day with Fergie

josh-duhamel-fergie-ellen.jpg"Safe Haven" star Josh Duhamel cranks up the romance factor with Julianne Hough in the Nicholas Sparks film, which was released on Valentine's Day -- but on "Ellen" on Thursday, Josh talks real-life love, Fergie.

"I bought her a nice gift. I bought her some earrings, took her to dinner and then made sweet, sweet love," he says of their Valentine's Day plans (though, awkwardly, the show was taped before V-Day). "It's Valentine's Day. You got to bring out your best stuff."

He admitted to Ellen that sometimes he and Fergie like to dress up in the bedroom, so she helpfully gifted him with a heart thong, which he gamely modeled for the audience. "I have a heart on!" he laughed.
