Paulina Gretzky is trading in walking down a runway to walk down the aisle! The model is engaged to professional golfer Dustin Johnson. Paulina, 24, and Dustin, 29, began dating early 2013 right after Dustin won the Tournament of Champions. Maybe Paulina is his good luck charm. The model is the daughter of Wayne Gretzy, a hockey player. So she's not one shy of athletes. The two shared the news on Twitter on Aug.18 with a photo from Dustin of the ring on Paulina's finger. "She said yes!!!" the golfer told fans. Congrats to the twosome.
