PHOTOS: On Friday, October 26, the Lot in West Hollywood, home to HBO’s True Blood, turned into a true haunted house as it played host to Fred & Jason’s Halloweenie 7, a benefit for The Gay Men’s Chorus of Los Angeles. Hundreds of guests enjoyed treats from Fatburger, Deleon Tequila Fuze and Moet, including Adam Lambert (above) Marissa Jaret Winokur, Peter Marc Jacobson, Bruce Vilanch, Carolyn Hennesy and Lance Bass, who taped his new Sirius XM radio show, Dirty Pop with Lance Bass, at the event.
