Tiger Woods' girlfriend Lindsey Vonn is a superstar in her own right, excelling at skiing. And she's still friendly to fans, reports say. She will be visiting with fans as Tiger attempts to win his first major golf tournament since the U.S. Open in 2008.

Lindsey is worried that Tiger will go back to his cheatin' ways, gossip currently holds. Vonn is allegedly worried that Tiger will go back to Elin Nordegren, particularly if the two go on vacation together-Vonn reportedly demanded to go along with them and the kids because she was afraid of what would happen if the two were left alone together.

Tiger has a history of cheating...so some fear makes sense.

However, other sources say the two are friendly...so the exact story is hard to straighten out. It's unclear if the two are pretending to be friendly or actually friendly.

"We're similar," Lindsey said of the two, denying rumors of any tension.

"We're both at the top of our sports, and we relate really well to each other."

Lindsey and Tiger don't plan on getting married, she said. When asked in an interview if she'd consider getting remarried, Vonn said,

"No thanks. I am definitely not getting married. To anyone."

Woods is playing in the 95th PGA Championship at the Oak Hill Country Club in Rochester, New York. Lindsey will sign autographs at the Ski Company in Rochester.

Woods will play on the PGA Tour at the WGC-Bridgestone Invitational 2013 Golf Tournament-and he is a favorite to win at Oak Hill.
