National Football League (NFL) superstar Tom Brady has credited his supermodel wife Gisele Bundchen for keeping their relationship strong for 12 years. Talking about the secret to their relationship, Brady told Good Morning America's Michael Strahan: "I give her [Gisele] a lot of credit for that. She's the one that supports the family and at the end of the day, makes a lot of sacrifices. She brings out the best version of me."

Brady, 43, shares two kids with Bundchen - Benjamin,11 and Vivian, eight. Brady is also a father to son John Edward with former partner Bridget Moynahan.

Brady also spoke about the importance of keeping his kids grounded and teaching them that they'll have to work hard in life. "Mom and Dad's life is very unique in this world. I don't want them to take those things for granted. I want them to make the impact in the world that they're going to make. But they're going to make it in their way, too," he said.
