Bill Gates Lets Loose At Sundance!

We never pegged Bill Gates as a sleazy billionaire, but we never thought Tiger Woods would end up a sex-addicted maniac, either!

The world’s richest man attended the Onitsuka Tiger Presents John Legend and The Roots at Bing Afterhours At House of Hype party at Sundance on Saturday night and was getting freaky with the girl pictured above!!

Onlookers said Gates was “freaking” the girl, named Renee, and danced ontop of his booth while enjoying John Legend.

The Microsoft co-founder had numerous people whispering, “Isn’t he married?” all night long.

And yes, Bill is married!

And has been for 16 years!!
