SAN FRANCISCO — Elon Musk attended a party at a Silicon Valley investor's house that got a little out of hand. <br />The Tesla and SpaceX CEO said he attended the now infamous sex party at investor Steve Jurvetson's residence, but that he didn't see anything naughty. <br /> <br />Apparently, Musk thought it was going to be a costume party. He was at the party for a few hours and bounced around 1 a.m. after talking some shop. <br />The party was mentioned in a Vanity Fair piece from Emily Chang's new book "Brotopia". In Chang's account, an anonymous "Jane Doe" said she saw a bunch of people cuddling and was offered some powdered goodies. <br />In November, Jurvetson parted ways with his venture firm Draper Fisher Jurvetson and took leave from the boards of Tesla and SpaceX, following an internal investigation.
