Despite denials that they're even involved, scandal-ridden golfer Tiger Woods is supposedly getting serious with his new girlfriend, Olympic gold medal skier Lindsey Vonn.

She was recently seen on his yacht off the coast of South Florida, so she must be recovering nicely from that injury she suffered last month -- the one that resulted in a trip on Tiger's jet.

Yachts, jets ... all she needs now is a gilded carriage to complete the sea/air/land trifecta.

Ironically named the “Privacy,” Woods uses the yacht once a year (because that's a practical use of a yacht) while he competes in Doral's Blue Monster course, where he won the 17th World Golf Championship title on Sunday. And according to the photographers who were camped outside day and night like they were waiting for a Black Friday sale, Vonn stayed with him on the boat the entire week.

For the first time in years, Woods was also spotted in late February with his ex-wife Elin Nordegren, and the former couple was apparently quite cordial. At least for the cameras (and their children).

Some of the tabloids speculated they might even be getting back together, but that's not the case. Elin's been busy seeing Swedish ice hockey star Douglas Murray (or, depending on which report you read, billionaire coal magnate Chris Cline) and putting the finishing touches on her sick new $12 million crib.
