Dustin Johnson and Paulina Gretzky now a perfect pair?

Rumors of cocaine use, wild partying and other misbehavior have plagued golfer Dustin Johnson and his sexy-selfie queen wife Paulina Gretzky since news of their engagement first hit the web. But on Sunday, at the World Golf Championships-Cadillac Championship at Trump National Doral, the young pair and their 7-week-old son looked like the picture-perfect couple.

After a six-month leave of absence for unexplained “personal challenges,” Johnson told reporters he was thrilled to win the Cadillac Championship.

“You know, Paulina and Tatum were waiting for me when I got done,” Johnson said at a press conference following his win. “That was the best part of the day for sure.”

Gretzky was overheard gushing about her relationship with the golfer.

"It's just unbelievable,” she said, according to a source. “Dustin's the best dad, he's my best friend. He's been so supportive with me and we're just there for each other.”

The two appeared to be on great terms, despite a report from Golf.com in Aug. 2014 that Johnson had slept with tour players’ wives.

Johnson told reporters that becoming a father has affected him both personally and professionally.

“It's hard to describe, but just from the first day he's born, your perspective on life completely changes,” he mused. “Things that were important aren't important anymore. He's kind of the only thing that's really important, and being there for him and being a role model for him. It kind of makes life a lot easier I think; just because there's just one thing that's kind of all you think about. It definitely simplifies stuff.”
