PHOTOS: Tiger Woods and girlfriend jet ski with his kids

Tiger Woods and Lindsey Vonn got into full-on summer mode over Memorial Day Weekend, taking the golfer's two kids -- Sam, 5, and Charlie, 4 -- out for a ride on a pair of jet skis on Sunday.

It seemed that Sam, 5, and Charlie, 4, were having a great time with the duo as they rode the motorized water vehicles through the water by Woods' Florida home, US magazine reported.

Sam sat in the seat in front of Vonn, while Woods kept a protective arm on son Charlie.

Golfer Tiger Woods and Olympic skiing champion Lindsey Vonn confirmed that they were dating in March.

Woods released a statement and photographs of the pair on his website and Facebook page before Vonn posted similar messages on her social media accounts.

Woods, a winner of 14 golf majors, divorced from his Swedish wife, Elin Nordegren, in 2010 after a highly-publicised sex scandal in which he publicly admitted to infidelity.

Vonn, who won the women's downhill gold medal at the 2010 Vancouver Winter Olympics, divorced from her husband Thomas Vonn in January.
