Paulina Gretzky Flaunts Engagement Ring At Tour Championship (PHOTOS)

We just can’t get over the size of Paulina Gretzky’s sparkler!

The newly engaged Instagram star showed off her incredible ring while watching the play of fiancé Dustin Johnson at the TOUR Championship in Altlanta, Ga. on Sunday.

Wayne Gretzky’s daughter, famous for her very revealing bikini shots, wore a simple black tank top, white pants and her aviator shades. She also returned to her signature long blond locks, after a brief return to a shorter ‘do.

But really, we just can’t take our eyes off her enormous rock.
