Tiger Woods and Lindsey Vonn enjoy some fun in the sun over the holiday weekend as they take his kids Jet-Skiing.

It looks like things are going well between Tiger Woods and Lindsey Vonn. The pair, who officially came Tiger Woods and Lindsey Vonnout of the dating closet back in March, has been seen out and about with Tiger's kids. Just a week ago, Woods and Vonn (with a bodyguard or two in tow) were spotted taking Tiger's little ones to school.

Vonn seems to be taking on her role as a step-mom-in-training really well. This past Sunday the pair took Tiger's kids out for some family fun in the sun. The duo were seen Jet-Skiing with Woods' and ex-wife Elin Nordegren's 4-year-old son Charlie and 5-year-old daughter Sam. Everyone looked like they were having a blast as they rode around the water by Woods' Florida home. Sam sat in front of Vonn, while Woods kept a protective arm on Charlie.

The couple's relationship has been growing strong ever since Vonn made the announcement on Facebook that they were indeed a couple, even including a professional photo to show just how serious they were about each other. Of course, it hasn't all been easy for Vonn. Not long after making the announcement on Facebook, she was seen hiding in a car just to avoid meeting up with Woods' ex-wife at Samantha's softball game.

We're hoping the days of Vonn hiding from the ex are long gone now that she's taking such a big part in the kids' lives. Who knows? Maybe we'll actually see the two ladies hanging out together at one of the kids' activities someday. It's not like Nordegren is unaware of the relationship between her ex and Vonn, especially considering how often the couple are being photographed together these days.
