Channing Tatum, PEOPLE’s former Sexiest Man Alive, is opening up on marriage, fatherhood and his wild ride to fame. Subscribe now for the exclusive interview and a shoot with the cast of Magic Mike XXL, only in PEOPLE!

Returning as a very chiseled Richie in the upcoming Magic Mike XXL, in theaters July 1, Joe Manganiello knew there was some work to be done to perfect his glorious stripper moves.

And who better to rehearse those moves on than his fiancée Sofia Vergara, right?

Well, sort of. “She was always covering herself in the sheets or running,” jokes the star, 38, in PEOPLE’s new cover story. “She’s like, ‘No! Get away!’ ”

“Come on, I’m playing a male stripper, it’s like, ‘What am I going to do? Not practice on her?’ ” he says with a laugh. “But it’s not to say that she asked for it. She did not ask for it.”

For Manganiello and Vergara, 42, who got engaged on the couple’s winter getaway to Hawaii, the countdown to the altar has been on for quite some time.

“I knew I was going to marry her. Even as early as the filming of Magic Mike XXL in September,” admits the actor. “I knew I was going to propose to her. I was planning it while we were filming.”
