Watch: Bieber raps with Wesley Bryan, Kevin Na at Quail Hollow

Tuesday was practice Day 2 at Quail Hollow ahead of the PGA Championship that kicks off Thursday. It was also, apparently, a good opportunity for pop sensation Justin Bieber to take a stroll with a few tour players.

Bieber joined Wesley Bryan, Bubba Watson, and Kevin Na during a portion of the trio's practice round. Bryan wasn't shy about putting his vocal chops on display, singing along with Bieber note for note to the pop star's hit "No Pressure."

Opening-round action tees off Thursday morning with American Jimmy Walker looking to defend his title.
