Celebrity Karaoke at the Heineken Green Room

Actor and comedian David Arquette hosted the uber-private Celebrity Karaoke at the Heineken Green Room on Sunday, January 20th. He was assisted in his hosting duties by outrageous personality Johnny Fayva. Both hosts had numerous performances on stage throughout the night. As Hollywood's elite belted out their favorite tunes, superstar DJ Samantha Ronson provided music and even jumped in to sing a few numbers.

Jason Reitman (Director of "Juno") was one of the first brave souls to take the stage. The crowd went crazy for his enthusiastic rendition. Esai Morales performed a fun duet with a friend and then Caroline Vreeland showed her range with her interpretations of two sultry Fiona Apple songs. Paris Hilton soon took over the stage to sing a few solos followed by a few group numbers with David Arquette and Johnny Fayva. She also brought Christine Lakin up to join in the fun.

Many celebs decided to stay out of the spotlight and enjoyed the vocal renderings of other attendees. Nicky Hilton, Dave Annable, DB Sweeney, Corinne Lazarz and Matthew Rhys kept it low key and cheered for the various performers while enjoying their Heinekens.
