Natalie Gulbis: Meet Dustin Johnson's girlfriend

So who is Natalie Gulbis? 

Gulbis, 28, has been playing golf since she was four years-old. When she was 14, she was the youngest player to qualify for an LPGA event (Michelle Wie later broke that mark). She later went on to play at the collegiate level for University of Arizona.

She only played one year for the school before deciding to go pro. In her first year, she finished second in Rookie of the Year points (2002). On her website, Natalie writes that she "found a permanent home on Tour where ever since I have been living dream!"

In 2005, she dated Pittsburgh Steelers quarterback Ben Roethlisberger. Gulbis appeared on "Celebrity Apprentice" in 2009. Unfortunately, she didn't win.
