"A lot of people are out to make me look like this womanizer," the actor tells PEOPLE in its upcoming issue. "The press has created this bachelor persona, but it's not really me. Hey, I take it as a compliment. It must be the first time in history where a sidekick on a show has this kind of persona offscreen."
So, PEOPLE asks, what is the Gospel According to Wilmer? "I've been sooo single for the past year," says the actor, 25, who is filming the eighth season of the FOX hit That '70s Show (premiering Nov. 2). "Right now, I just love working."
He recently wrapped two movies, has a lead role on the animated series Handy Manny, and is launching a clothing line in February.
"I won't have a day off until Dec. 31," he says.
Still, he says, he plans to find time for a Mrs. Valderrama in the not-too-distant future: "I'm open-minded. I'd love to have kids soon."
And what about those famous dates?
Mandy Moore: "I was with her for almost two years. When it ended, it took me another four years to even give it a shot again. That was tough."

Ashlee Simpson: "We've been friends for about 51⁄2 years. All of a sudden we couldn't be in the same room before people were saying we were making out." They did not, he says; they remain just friends.
Jaime Pressly: "There is no story there. All of us on the show have been friends with Jaime for many, many years. ... Jaime is an amazing girl."
