Tiger Woods and Lindsey Vonn spent Memorial Day taking the golfer's children jet skiing.

The couple took Sam, 6, and Charlie, 4 on a ride around a lake in Jupiter, Florida, The New York Post reported. 

The 28-year-old blonde beauty was pictured in a small bikini featuring a black bottom and blue top. She was strapped tight in a life vest as she motored around with Charlie on her lap.

Woods was all smiles, dressed in black swim trunks and dark sunglasses. Sam was buttoned up in her life vest and rode around the lake with her hands on Woods' jet ski.

Vonn's leg was not in a cast and appears to be healing after she tore her anterior-cruciate and medial collateral knee ligaments during the Alpine Ski Championships back in February.

Vonn and Woods announced their relationship back in March via the golfer's Facebook page.

In a note to Woods' fans, he wrote: "Lindsey and I have been friends for some time, but over the last few months we have become very close and are now dating. We thank you for your support and for respecting our privacy. We want to continue our relationship, privately, as an ordinary couple and continue to compete as athletes."

Back on Nov. 27, 2009, Woods' ex-wife Ellin Nordegren discovered that the golfer had cheated on him after discovering one of his mistress's phone number on his cell phone. Tiger attempted to leave his home after Nordegren found out about the mistress, but crashed his car into a fire hydrant.

Woods reportedly confessed to Nordegren and said he slept with more than 120 women throughout their marriage. 

Nordegren has since moved on, and is currently dating billionare, Chris Cline.
