Katie Holmes, Tom Cruise Katie Holmes, Tom Cruise

After four years of marriage and a baby, Katie Holmes still says she's starstruck by her husband Tom Cruise, according to New York Magazine.

Can Katie Holmes pull off Jackie Kennedy?

But would Holmes ever consider acting alongside Cruise? "Well, we do collaborate on everything at home. But I mean, he's Tom Cruise! His body of work is incredible. Every movie he's done has done really well. I look back, and everything's a classic."

Holmes says she takes advantage of her megastar hubby by hitting him up for acting advice. "I definitely come home and say to him, 'So, imagine a scene ... how would you play it?' And he's helpful and sweet and gracious," she says. "He's quite an incredible human being."

Holmes will be next seen as Jackie Kennedy in the upcoming History Channel miniseries The Kennedys.
