Hitting the green for dad! Tiger Woods got an adorable surprise at The Masters Preview Day in Augusta, Ga. on Tuesday, April 7. 

The golf pro, 39, was working on his game ahead of this weekend's 2015 Masters Tournament, when he was visited by his two kids and his girlfriend of two years Lindsey Vonn. See more adorable photos from the outing.

The champion skier, 30, arrived at the Augusta National Golf Club with Woods' children in tow, whom the golfer shares with his ex-wife Elin Nordegren. Woods' and Nordegren's daughter Sam, 7, grinned as she supported her father, matching his bright pink golf shirt in a pink polo of her own.

Woods' younger son, 6-year-old Charlie, hugged his dad and held Vonn's hand as they walked the course. The Olympic athlete has been spending time with the kids since she started dating Woods in early 2013. Vonn was previously married to fellow skier Thomas Vonn for four years, but the two filed for divorce in 2011. 

Woods famously went through his own messy divorce in 2010, following his infamous cheating scandal. The athlete's affairs with multiple women ended his six-year marriage to Nordegren, who shares custody of Charlie and Sam.

While he once dominated the Masters Tournament, winning the competition in 1997, 2001, 2002, and 2005, Woods has not been competing at the level that he used to as of late. He has been hitting high scores in recent tournaments, but said he's ready for this week's Masters.

"I worked my ass off," he told reporters on Tuesday of his Masters prep. "That's the easiest way to kind of describe it. I worked hard."

Woods may be getting some extra luck in the form of Sam and Charlie, as the two kids will caddie for the golfer at Wednesday's Par 3 Contest. "Charlie has seen me win a golf tournament before. Sam, actually she was there at the U.S. Open in 2008, but doesn't remember it," Woods said on Tuesday of his little ones. "It's nice to be able to share these things with my family, and it just means the world to me. They are excited, I'm excited and can't wait to go out there."
