Reid probably turned the most heads for her outfit, rocking a barely-there Greek goddess outfit that showed off her extremely slender figure. The 40-year-old actress rocked the two-piece look with some transparent heels.

Pauly D and Aubrey O'Day showed up in totally opposite costumes, with Pauly D rocking some sort of dark grim-reaper ensemble and O'Day opting for a rainbow angel/unicorn situation. The couple packed on the PDA for the cameras, natch.
