Lindsey Vonn And Tiger Woods Relationship Update: Is Lindsey Worried That Tiger Still Has Feelings For Elin Nordegren?

World No. 1 golfer Tiger Woods and Olympic gold medal skier Lindsey Vonn have been dating since March and while the couple continues to build a seemingly strong relationship, multiple reports indicate that the 28-year-old Vonn may feel as though she's not the only woman on TW's mind.

While Vonn will surely be in attendance at the upcoming PGA Championship - where her boyfriend hopes he can snap a streak of 17 major championships without a victory - The National Ledger reports that Vonn is worried that Tiger still has strong feelings for ex-wife and mother to his children Elin Nordegren.

Woods and Elin Nordegren were divorced in 2010 after a very public split that included numerous women being named as Woods' lovers, it was an epic celebrity cheating scandal and the tabloid story seems to follow the logic that Vonn should be worried.

Lindsey is worried Tiger may go back to his ex-wife Elin Nordegren and she is also supposedly worried about Tiger returning to his former cheating ways.

In addition to Vonn possibly growing weary of Woods' feelings towards Elin, United Press International notes that the only thing that would end the relationship between the athletic super couple would be Tiger Woods sleeping with his former partner, something Vonn hasn't ruled out according to a source.

"Lindsey is convinced that Tiger still has feelings for Elin," an unnamed source told UPI. "And if he got the chance, he would dump Lindsey in a flash and get back together with her."

Though rumors concerning Vonn's alleged worries about Tiger's feelings toward Elin Nordegren will certainly spark interest amongst those who follow the celebrity duo, the indication that Lindsey is fearing Tiger will leave her for his ex comes as a bit of a surprise considering the Gold medalist was clearly proud of her beau's accomplishment at the recent WGC Bridgestone Invitational.

Woods blitzed past the field for a seven-stroke victory thanks in large part to firing a second round 61. Noticeably happy with his performance, Vonn referred to Tiger as the 'Greatest of All-Time' on her Twitter page after Tiger won his 79^th career event and his eighth victory at the Bridgestone.

Despite these rumors that Tiger may be interested in pursuing Elin Nordegren once again, things seem to be going great for Lindsey Vonn and Woods and with the PGA Championship just days away, you can be sure Ms. Vonn will be there supporting her man as he aims for Major Championship No. 15.
