Between Deflategate and all those divorce rumors, it's safe to say 2015 hasn't exactly been the smoothest for Tom Brady.

ET caught up with the handsome 38-year-old quarterback in New York City on Tuesday night, when he was announced as Tag Heuer's new brand ambassador. Brady talked about Tag Heuer's slogan, "Don't Crack Under Pressure," which is especially relevant given the eventful year he's had.

"Well, I've had a lot of events in my life that have motivated me," Brady said about how he's been able to push through all the drama. "Starting with high school -- the love of the game, the love of my sport, it started in high school. There's challenges in college. There's challenges when I started professionally. There's been challenges when I injure myself. There's challenges this off season, but, I think all of those things reinforce what your belief systems are."

"You know, my motivation is to be the best that I can be," he stressed. "To be the best I can for my teammates, and never let my teammates down. I take my job very seriously. I put a lot into it. I'm happy we're off to a good start."

After successfully overturning his Deflategate suspension in September, Brady's New England Patriots have had a pretty amazing season. They're currently 4-0 heading into this Sunday's game against the Indianapolis Colts.

The team's winning streak is obviously a cause for celebration when it comes to Brady's A-list pals, Boston natives Ben Affleck, Matt Damon, and Mark Wahlberg. Brady said he's grateful for their continued support.

"I've been a displaced Californian living in Boston and realizing the roots and how strong the Boston culture is, so that's where I've been for 16 years of my life," Brady explained. "That's where my kids were born, and that's where I'll live, so it's a great place to live. We live in a great neighborhood, and there's a lot of roots in Boston, so [those] guys in particular, I've gotten to know over the years and they're all friends. They believe in what we're doing, and it's great to have such great support from, you know, all those guys."

"That is the Boston crew man," he smiled.

Though presumably, Brady wasn't too pleased at getting pulled into 43-year-old Affleck's nanny drama in August, when a picture leaked of the actor's former nanny, 28-year-old Christine Ouzounian, wearing his four Super Bowl rings on her right hand. ET confirmed Ouzounian – who reportedly had an affair with the Oscar winner, which his rep has strongly denied -- was on the private jet with Affleck and Brady as the group headed to Las Vegas for a charity poker tournament in late June without Affleck’s kids.
