What a good guy Tom Brady is! The NFL quarterback just shaved his head for charity — and we're loving his new look. Watch the video above to see Tom with a shaved head!

The 40-year-old debuted his new look via Instagram on Thursday, March 8. "They call me Buzzy… Tom Buzzy. ?What a fun #SavingByShaving event today. It was an honor to join the fun and support @DanaFarber and all the great work they do! Thanks for the invite @coachhale5 (Rob Hale) and thank you @piniandco for the haircut! ?" he captioned the photo. At the Saving by Shaving event in Boston, Tom surprised the crowd as a "mystery guest." Imagine being there with Tom Brady? We wonder what his wife, Gisele Bündchen, thinks of his new look!

Now that football season is over, Tom has more time for events like these, as well as time to be with his wife and kids, Jack, 10, Benjamin, 8 and Vivian, 5. In fact, Gisele is bugging him to retire sooner rather than later.

In a previous interview, Tom opened up about how Gisele feels about his career. "I think we go back and forth," he shared last fall. "She'll always say to me, 'Ten years ago you said it was only going to be another ten years. Now it's ten years, and now you're saying another five years.'"

Gisele has been candid about her husband's injuries in the past, and why she'd like him to hang up his cleats. "He had a concussion last year. I mean he has concussions pretty much every — I mean we don't talk about — but he does have concussions," she said. "I don't really think it's a healthy thing for your body to go through like, through that kind of aggression like, all the time — that cannot be healthy for you, right?"

She added, "I mean I'm planning on having him be healthy and do a lot of fun things when we're like 100, I hope." We wonder if he'll have hair when he's 100…
