Lindsey Vonn Tiger Woods Twitter Comment: ‘So Proud!’ Of ‘Greatest Of All Time’ Boyfriend, But Worried He Will Cheat With Ex Wife Elin Nordegren?

Lindsey Vonn took to Twitter to comment on Tiger Woods' 79th PGA Tour title at the World Golf Championships-Bridgestone Invitational on Sunday, August 4. She had nothing but praise for her boyfriend, but is she secretly worried he will cheat on her with his ex-wife Elin Nordegren?

Voon took to Twitter to gush about her boyfriend's win at the PGA Tour. "So proud!!!!" she tweeted of Woods' victory, as well as the number 79 for the 79th PGA Tour, and the hashtag "#GOAT," which is an acronym for "Greatest Of All Time," Yahoo! reports.

According to the website, Lindsey, 28, has often been spotted supporting Woods at his golf tournaments in recent months. 

Despite her constant support and enthusiasm for her boyfriend, UPI.com reports that Lindsey knows one thing that would end their relationship: if Tiger Woods cheats on her with his ex-wife, Elin Nordegren.

"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, UPI reports.

The website also reports that Vonn declared she would never get married again, after 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."
