Gisele Bundchen says she stuck by her husband, Tom Brady, throughout both his Deflategate scandal and all the divorce rumors earlier this year because he's "a good man."

"I think we've been through a few tough times together," Bundchen told Charlie Rose on Tuesday's CBS This Morning of her relationship with Brady. "That's when you know who are your friends, who loves you."

"My father always says, 'The quality of your life depends on the quality of your relationships,'" the supermodel added. "I think no matter how challenging it was, we've always been supportive of one another."

Bundchen also shared that, despite everything, she knew her husband, and the father of her two children, was a "kind man."

"He is, he's kind. He's the good man," she gushed.

Bundchen later revealed that her six-year marriage to Brady almost didn't happen.

In 2007, Bundchen had just started dating Brady when she learned he was having a baby with his ex-girlfriend, actress Bridget Moynahan. She admits that she nearly called it quits with the NFL pro.

"It was a challenging thing because here I am thinking I'm dating this guy and we met... and everything's great. And then this happens," she recalled. "I didn't know what to do. It was kind of one of those moments of like, 'Do I just run away?'"

Benjamin Brady, Moynahan and Brady's son, is now eight years old, and Bundchen insists that the drama is all behind her. "I think, you know, now eight years later, I couldn't have asked for a sweeter bonus child," she said.

While Bundchen and Brady both work hard at being the best at their jobs, she says "he's much more competitive," because her job is "more about collaboration."

She's been the highest-paid supermodel since 2002 but doesn't believe it's all due to her looks. "I think it's because of my personality. I think I've never complained," she explained. "If I choose to say yes to something and if someone is putting their trust in me, I don't want to disappoint anybody."
