Question: What was the most shocking aspect of porn star Sasha Grey’s 21st-birthday bash at Tao?

A) Her demure black party dress

B) Overhearing party guest Billy Corgan’s treatise on the 60-year cycle of music genres

C) Watching comped bottles sit almost untouched

D) Two gorgeous ladies adorning an old man at the next table

According to Sasha’s crew (which also included AJ from Backstreet Boys and a quick hello from Lance Bass), the answer is “D.” Bucking yet another stereotype, Sasha’s party was super-chill (inside the velvet rope, at least). If you didn’t know her métier, you’d think she was just one in a group of hipster LA intellectuals who loved taking pictures of each other. So when the next table over started grinding, the Los Angelenos pointed and giggled, turning the camera from themselves to the real party.
