Matthew Morrison Channels Roger Rabbit for Halloween & Parties With 'Glee' Cast (PHOTOS)
His Glee co-stars came out in full force for the Bing party with Mark Salling, Dianna Agron, Chris Colfer, Darren Criss, Amber Riley, Naya Rivera, and Kevin Mchale, who all sipped on SVEDKA TRICK_BOT cocktails all night.
Morrison took the stage to sing a few songs but the birthday boy got a surprise of his own when his model girlfriend Renee Puente got in touch with her inner Marilyn Monroe to coo him a chorus of "Happy Birthday."
Of course, Matthew wasn't the only celeb partying the night away in celebration of Halloween. Check out pics of Kim Kardashian dressed as Poison Ivy, a very sexy version of a famous Batman villain.
