Maybe they're getting serious?

Just days after Tiger Woods and Lindsey Vonn made their red carpet debut at the Met Gala in New York City, they were spotted relaxing on the golfer's yacht in Florida on Tuesday-with his kids!

The happy couple looked relaxed as they took photos and fished off the back of the boat with Woods's children (not pictured here) from his marriage to Elin Nordegren, daughter Sam, 6, and son Charlie, 4.

Woods and Vonn announced they were dating in March, and a month later, she cheered him on at the Masters.

"Not only are they a couple, but they are a very sweet and loving couple," said Michael Strahan, who spent time with Vonn and Woods at the Met Gala. "Really, a lovely couple."
