Considering her adopted son Louis is the most important man in her life, Sandra Bullock hasn't felt the need to add another since her highly-publicized divorce from cheating ex Jesse James in 2010. The actress sparked rumors when she took a vacation with her The Proposal costar Ryan Reynolds -- who's now married to Blake Lively -- in August 2011, but it turned out to be of the platonic variety. And, she says, her life is dedicated to son Louis now. "He's made me a better person," Bullock told iVillage. "He's made me enjoy life in a way I never thought possible."
