Josh Duhamel is constantly looking for new ways to surprise his wife Fergie, and Ellen DeGeneres shared a sexy suggestion with the Safe Haven actor when he swung by The Ellen DeGeneres Show in an episode airing Friday, Feb. 15.

"Valentine's Day wad great. I bought her a nice gift. I bought her some earrings, took her to dinner and then made sweet, sweet love," Duhamel, 40, said of his wife of four years.

"What time around was that?" DeGeneres, 55, asked.

"Anywhere between 9 and 2 a.m.," the actor replied. "It's Valentine's Day. You got to bring out your best stuff."

"Speaking of that," DeGeneres said, "she said that she always surprises you with naughty things. Do you know what I'm talking about?"

"Yeah, we do a lot of dressing up, it seems," the 6-foot-4 actor admitted.

The comedienne then presented Duhamel with a metallic red thong in the shape of a heart. "That might cover it up," Duhamel said after putting it over his pants. "I have a 'heart on.'"

DeGeneres laughed and said, "I knew you were going to say that!"
