Infamous Swinger Vince Vaughn, 39, wants to trade in his single-guy status for kids with fiancee Kyla Weber. "It's the first time that I really want to have kids," Vaughn tells People. "I've been very fortunate in my career, and my life has been about that for so long that you get bored of it. You're ready for your life to be about other people and other things." Appropriately, Vaughn next stars with buddy Jon Favreau in Couples Retreat. (Photo: WENN)
