Gisele says Tom's love child "strengthened" their relationship

In an exclusive interview with this month's Vanity Fair, supermodel Gisele Bundchen reveals her feelings on her new marriage and being a stepmother, according to People magazine. Bundchen married New England Patriots quarterback Tom Brady in February, 18 months after Brady's ex, actress Bridget Moynahan, gave birth to the football star's son. Brady and Bundchen had only been dating for two months when news of Moynahan's pregnancy emerged, and the supermodel reflects that she almost called it quits then and there. ""[I]t was a very challenging situation," Bundchen says. "Obviously, in the beginning, it's not the ideal thing." But ultimately, the new bride admits that staying with Brady, "was a blessing, because otherwise I don't think I would have known what he was made of, and he wouldn't have known what I was made of." In the interview, the world's highest paid supermodel also praises Brady's integrity and how the circumstances showed her that Brady was a good person despite a difficult situation. "I was like, You have the heart in a good place! It made me feel more in love with him; it made me realize who he was," she gushes. The couple are due to celebrate their recent nuptials with close family and friends in Costa Rica this Friday, and Bundchen is quick to insist that she has no doubts about her future with Brady: "Our relationship has become so much stronger, and I think I wouldn't be as certain as I am today if it weren't for that."
