The one thing that Lindsey Vonn says could end her relationship with Tiger Woods is sex with his ex-wife, Elin Nordegren.
Nordegren has given her blessing to the couple before, reportedly, and Vonn has been spotted with their children.
Even still, Vonn says that she does not think Nordegren would be above breaking up their relationship behind her back to get back at her ex-husband.
“Lindsey is convinced that Tiger still has feelings for Elin and, if he got the chance, he would dump Lindsey in a flash and get back together with her,” a source said.
Woods' cheating history aside, Vonn had said she would never get married again divorcing her first husband.
“I’m not an idiot; I try not to look, but I see what people say about me on Facebook,” Vonn said. “I see other things written. But I don’t care. I learned a while ago from my divorce that my happiness is the most important thing. That’s all I can control. And right now, I’m happy.”
