Tiger Woods and his new flame Lindsey Vonn have quickly taken a dive in to serious territory, hanging with Woods' children on his yacht Tuesday in Palm Beach, Fla.

The couple, who just confirmed their relationship in March, spent a day on the golf pro's yacht. Woods' children with ex-wife Elin Nordegen, were onboard to enjoy the sun, according to the Daily Mail (SEE PHOTOS).

Vonn seemed happy to be hanging with her new beau and his children. The bikini-clad blond beauty took photos of Woods and his children fishing together. Woods and Vonn also just recently made their first public appearance together at the Met gala. The yacht trip comes after Woods' win at the Players Championship.

Woods, who has reportedly been seeing Vonn since November, has been linked to various women in the past. Rachel Uchitel, Woods' alleged mistress, was reportedly the topic of an argument that followed with the Woods' split with his wife. Porn star Joslyn James was also one of Woods' alleged mistresses.

Vonn is a World Cup alpine ski racer and gold medalist who competed with the United States Ski Team. She was married to fellow Olympian Thomas Vonn from 2007 to 2011.

Vonn appeared in a 2010 edition of Sports Illustrated's swimsuit edition, featuring winter Olympians in 2010. Vonn also made Maxim's Hot 100 list the same year.
