Caleb Watson, Bubba Watson

Bubba Watson has Bieber fever, and he's passing the condition onto his young son. Already a strange union within the celebrity world, Watson and Justin Bieber have hung out several times in the past.

But in a recent Twitter post from the PGA Tour star, Bieber is caught giving some drum lessons to Watson's son, Caleb. Caleb Watson is a common sight on the PGA Tour and has even joined his father on the course in The Masters' Par-3 Contest.

Now he's going to music school:

Bubba Watson is in L.A. for the Northern Trust Open, so he's probably making the rounds and visiting his famous friends in the area. Few of his engagements will draw as much attention and curiosity as this meet-up with the Biebs.

If Bieber is smart, he'll trade Bubba some gratis drum lessons in exchange for some guidance on the links. Last summer, TMZ caught Bieber in the midst of a difficult day on the course, where he threw his club into the ground and took several mulligans on bad shots before taking one he liked.

Practice makes perfect. Patience helps, too.
