Heidi Montag: Beer Pong Champion?

Former boybander Lance Bass, 29, hosted an Olympic-themed bash/viewing party at the Haute House in Los Angeles earlier this month.

Guests included The Hills star Heidi Montag, 21, and The Sopranos actress Jamie-Lynn Sigler, 27. The pair competed in popular drinking games like Beer Pong as they rooted on Team USA.

“Heidi actually did pretty well,” one partygoer tells Life & Style. “But it was Jamie-Lynn who killed it.”

Other pictures include Jamie-Lynn with Vanessa Minnillo (Nick Lachey‘s girlfriend), and Lipstick Jungle star Lindsay Price at the launch of of the new “Tide and Downy Total Care” at the pool deck of NYC’s Empire Hotel on Tuesday.
