Rob Gronkowski took it all off for charity on Sunday -- his hair, that is.
The Patriots tight end got his head shaved at the Kids Cancer Buzz-Off to help raise money for children with cancer.
Of course, Gronk found a way to work in a shirtless reference on his Twitter account soon after his head was freshly shaven.
My final look for summer time! Oo gonna be looking smooth with that shirt off with this hair cut! twitter.comRobGronkowski Rob Gronkowski (@RobGronkowski) June 3, 2012
