“We’re sickening,” admits Bruce Willis. “We make out in public. I know there’s some rule that you’re not supposed to be doing — what is it? Public displays of affection?”

“PDA,” says says his 32-year-old lingerie model wife Emma Heming. The newlyweds say they are “mad crazy in love,” in the new issue of W, out June 23.

Acknowledging his transformation, Bruce tells the mag: “I went from ‘F*ck love’ to ‘Love is truly the answer.”

He adds: “I spent the last 10 years single and, for the most part, unhappy. In a dark place. I never thought that being with someone else was the answer. I would say, ‘I’m alone, but I’m not lonely.’ But I was just kidding myself. Then I started hanging around Emma, and on a day-to-day basis my life became much happier.”

A few more highlights:

Bruce On Their Relationship With Demi, Ashton and the Kids: “We’ve become like a tribe. It’s generated a lot of interest because everyone can understand resentment and envy in the breakup of a marriage, but they don’t understand how I can get along with my ex like that. Demi and I made a choice to put the kids first, and we’re really lucky that it turns out we all have fun together. I still love her, and I have a lot of respect for how she lives her life.”

Bruce On Their W Photo Shoot: “Oh, it was awkward. We did stuff that I know a lot of other actors would not have done. Had I done it with another model I don’t know that I would have been as into it.”

On His Feelings Toward Emma: “I hear so many people in relationships say, ‘I just need a couple of days away, or even an hour away.’ But I don’t want to be away from Emma at all. It’s the most singular relationship I’ve ever had in my life.”
