Lindsay Vonn announced the mutual breakup via Facebook. She cites their hectic schedules as the primary reason for their decision.
The Huffington Post reported that the 14-time major golf winner accompanied Vonn in Italy where the Olympic gold medalist broke the World Cup record. She has been a regular in the crowd at his majors.
Just last April, Vonn attended the Augusta National Golf Club with Woods' two children.
In the same month, Vonn joined Seth Meyers on the Late Show where she discussed her 'love' for golf.
Woods has not won since 2013 and will fall out of the top 120 in the next world ranking.
