Things got off to a rocky start for Gisele Bündchen and husband Tom Brady.

In case you need a refresher, the NFL star's ex, Bridget Moynahan, announced in 2007 that she was pregnant with the athlete's child less than three months into his relationship with the supermodel.

Tom and Bridget in 2005.

"It was a challenging thing because here I am, you know, thinking, I'm dating this guy, we met, and we started dating and everything is great and then this happens," the 35-year-old recalls in a new interview.

"So, then I felt like I didn't know what to do. It was kind of one of those moments of like, 'Do I just run away?'"

In August of 2007, Bridget gave birth to the pair's son, John. "I think, now, eight years later, I couldn't have asked for a sweeter bonus child," Gisele admits.

As we all know, the brunette beauty and Tom went on to marry in 2009 and welcome two children, Benjamin, 5, and Vivian, 2. But they've certainly experienced their fair share of rough patches.

"My father always says 'the quality of your life depends on the quality of your relationships,'" Gisele tells CBS This Morning's Charlie Rose, referencing both frequent divorce rumors and Tom's recent NFL drama. "I'm so grateful to be where I am right now. I feel fulfilled."
