When Tiger Woods and Lindsey Vonn split over a week ago, the Olympic skier, in a Facebook post, blamed it on their 'incredibly hectic lives that force us to spend a majority of our time apart'.

However, Woods, who was infamously caught cheating on his then wife Elin Nordegren in 2009 with several women, it seems, has gone back to his bad habits. According to a report in British tabloid Daily Mail, Woods and Vonn split because the golfer cheated on the ski champ.

Sex cheat
"He (Woods) had a relapse in the sex department," the report quoted a close friend of Vonn saying about Woods. The friend revealed that Woods had a one-night stand following his elimination from the San Diego-based Farmer's Insurance Classic in February, and Vonn found out about it.

Shockingly though, instead of hiding it from Vonn, like he did back then with Nordegren, this time Woods is said to have admitted to it even before he was caught.

The friend added: "He doesn't even see it as cheating. It's just stress relief. It's hard for him to see that he's bad. Maybe he's not. He's not married to Lindsey. But he also won't get her back. She's another strong woman like Elin, who respects herself too much."
