Lance Bass threw an Olympics viewing party for 300 of his friends at his house in the Hollywood Hills. The attire for the evening? Vintage sportswear, of course. (Think high socks and headbands!) The revelers even indulged in some athletics of their own, namely beer pong and a flip cup tournament with multiple teams. Bass and good friend Jamie Lynn Sigler munched on burritos from Chipotle during the bash, which also drew out Heidi Montag and J.C. Chasez. If the games weren't enough, the host fully embraced the athletic theme with his decor: He outfitted his front yard with a big, faux Olympic torch.
