In null a stepmom-in-training?
Well, let's not go that far just yet, but she is spending some quality time with boyfriend null' kids!
On Sunday, the 28-year-old Olympic skier and her 37-year-old golfer beau went jet-skiing in Jupiter, Fla., with Tiger and ex-wife null's son Charlie, 4, and daughter Sam, 5.
Looks like Lindsey is becoming more comfortable with Tiger's kids as the couple's romance blossoms—just two months ago, the skier stayed in the car during Sam's soccer game. By last month, she and Tiger were comfortable playing house, even taking Sam and Charlie to school in North Palm Beach. And now, Vonn seems to be enjoying some fun in the sun with the Tiger's cubs!
