Bieber mocks Brady's hair in rap

Even Justin Bieber is making fun of Tom Brady's hair.

The New England Patriots quarterback's long locks have been mocked for resembling that of the teen pop sensation — and now Bieber himself is piling on.

In a video posted by Bieber late Wednesday, he raps: "Sacked like a sacker. Call up Mr. Brady. Tell him to leave his hair to the guy who sings 'Baby."'

Brady has stated that he intended no similarity to Bieber's haircut and was merely going for a different look this season.
