He may be one of the NFL's leading quarterbacks, but it's Tom Brady's supermodel wife, Gisele Bündchen, who calls the shots when it comes to his hair.

When a Massachusetts radio host recently tried to persuade the New England Patriots star to ditch his Justin Bieber do and return to his clean-cut roots, Brady balked and said, "Ah, you'll have to speak to my wife about that," the Boston Herald reports.

Scissors, please!

Brady -- who, for the record, is a 32-year-old grown-up -- has been mocked in the Beantown press ever since he showed up at the June NBA playoffs sporting a Bieberlike shag.

Some Hub stylists complained the mane was too young for the athlete's matinee idol face, but to be fair, Brady isn't Bieber's only adult imitator.

How you doin', 43-year-old David Schwimmer?

Crooner Michael Bublé, 35, also unveiled a version of the teen idol's shaggy locks in a new music video, but his styling, which included a signature Bieber hoodie, was in jest.

As was Jimmy Fallon's Sept. 24 "Late Night" tribute, in which he played Bieber reflecting upon his recent "CSI" acting gig.

Meanwhile, Brady has made no comment on whether he likes the look or if he's just keen on making Mrs. Brady happy.

Brady does, however, have a least one other, um, fan of his long, sun-kissed tresses.

"Nice haircut, Brady," Bieber quipped when asked by the Herald for a statement on the athlete's mop top. "Dude's got some golden locks. Haha!"

So big, strong NFL dude: That's you getting laughed at by a 16-year-old.
