Tom Brady and wife Gisele Bündchen celebrated their 12th wedding anniversary in February

Tom Brady is crediting his wife Gisele Bündchen with keeping their marriage strong.

The pair celebrated their 12-year wedding anniversary in February, and in a new interview with Good Morning America, Brady, 43, tells Michael Strahan about the secret to their relationship.

"I give her a lot of credit for that," says Brady, who shares two kids with the model, son Benjamin Rein, 11, and daughter Vivian Lake, 8. (He is also dad to 13-year-old son John "Jack" Edward with ex Bridget Moynahan.)

"She's the one that, you know, supports the family and, at the end of the day, makes a lot of sacrifices," he adds. "She brings out the best version of me."

Brady also opened up about keeping his kids "grounded" as they grow up, making sure that they know they'll have to "work hard" in life. He explains, "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 gonna make. But they're gonna make it in their way, too."
