The surprising admission that she has never been introduced to the mother of her husband's son comes during a wide-ranging interview in the May issue of "Vanity Fair," on sale April 7.
“I understand that he has a mom, and I respect that, but to me it’s not like because somebody else delivered him, that’s not my child," she says of John Edward Thomas Moynahan, her husband's son with the "Sex and the City" star. "I feel it is, 100 percent. I want him to have a great relationship with his mom, because that’s important, but I love him the same way as if he were mine.”

So what was it like when, after she and Brady had just started dating, she found out that her new quarterback boyfriend's actress ex was pregnant?
“It was definitely a surprise for both of us,” she says. “In the beginning you’re living this romantic fantasy; you’re thinking, This can’t be true, it’s so good! And then, Whoops—wake-up call!”
Of course Gisele has some experience with high-profile exes, having broken up with Oscar-nominated actor Leonardo DiCaprio after several years together. “Leo is a really wonderful person. We still speak sometimes, and I’m friends with his mom. He still has one of my dogs," she says. "We were very young, and we grew together in a lot of ways. We were just not meant to be boyfriend and girlfriend, but I respect him enormously, and I wish him nothing but the best.”
