Penacoli congratulated the new dad on the birth of fourth daughter, Mabel Ray. Willis laughed, "Sleep is elusive. It's like working nights! Nothing else in the world makes you this happy than to have a little baby."
As for his three girls with ex-wife Demi Moore -- Rumer, 23; Scout, 20; and Tallulah, 18 -- Willis says he is looking forward to their weddings. "I perceive many weddings! My girls can pick good guys." Bruce added that Moore is "doing great" after her stint in rehab.
The action hero is also excited about starring in the sequel, "G.I. Joe: Retaliation." Did he play with the toys as a kid? "Are you kidding? I blew 'em up! Put them on arrows. And the fact I used to play with G.I. Joes, and now I'm in a movie... it's an honor!"
Check out Bruce in "G.I. Joe: Retaliation," marching into theaters June 29.
