Lindsay Vonn, Olympic skier and current girlfriend of Tiger Woods, is getting some advice from the golfer's mistresses on how to handle being in a relationship with the famous athlete. 

Devon "XXX" James is a famous porn start better known as Woods' 16th mistress and told Vonn that she should watch her back, according to FOX. 

"You know when the pics came out of Tiger and his new girlfriend - somewhere, 15 other girls were going, 'Huh? I thought I was his girlfriend!' " James said Tuesday.

James added that she was surprised to discover that Woods was dating Vonn since the blonde-haired skier isn't really his type. 

"I thought he would have picked a woman who was more petite and not someone who is more muscular and has a bigger head than his," James said. "Maybe his taste has changed since [ex-wife Elin Nordegren] and the 27 mistresses."

Rachel Uchitel is another mistress whose text messages sparked the infamous Thanksgiving 2009 incident between Woods and then-wife Nordegren, where he smashing his SUV into a tree. Uchitel posted a message on her Twitter account about Woods and Vonn.  

"Everyone deserves a second chance," Uchitel tweeted on Tuesday. "No exceptions to that rule, in my humble opinion."

Woods and Tiger announced their relationship via Facebook on Monday.

 "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," Woods said. 

The 28-year-old newly divorced gold medalist and the 37-year-old golfer have been romantically linked since last November and were most recently photographed spending time together on Woods' private yacht.

"Our relationship evolved from a friendship into something more over these past few months and it has made me very happy," Vonn said. 

A source told Us Weekly  the couple is really happy in the beginning stages of the relationship and that they haven't moved in together yet. 

"He confessed everything in his past to her and stuff - they're really into each other," the source said.
