Paulina Gretzky Wakeboards In A Tiny Bikini (VIDEO)

Paulina Gretzky sure is one sporty gal!

Just a couple of days after working on her golf swing (and wearing the shortest tennis skirt ever), Wayne Gretzky's eldest daughter took her athletic self on the water for her first wakeboarding lesson and obviously, girl was wearing the tiniest black bikini known to mankind.

On Wednesday night, the 25-year-old Golf Digest cover gal posted an Instagram video of herself riding the surf and by the looks of things, the Maxim babe was a total natural!

"First Time Wake Surfing," Dustin Johnson's fiancé captioned the pic. (Note: Paulina was actually wakeboarding as she was holding onto a rope that was attached to the boat. Wakesurfers drop the rope after they lift out of the water to ride the surf.)

It's been a very sporty summer for Paulina: two weeks ago, the pretty blond posted a pic of herself in a sleek wetsuit while hanging on to a surfboard (presumably because she was about to go surfing, obvi) and she got in a great workout when she posed for the controversial Golf Digest cover.

But the L.A.-native hasn't forgotten to show off her fit figure in a series of sexy bikinis.
