It was one hell of a party at the The Sayers Club in Hollywood last night!
GQ and Guess teamed up to throw a wild party for the highly anticipated GQ November music issue!
Joe Jonas and Jamie-Lynn Sigler were looking extra chic in their Guess attire.
And they weren't the only ones! The list of party-goers included Dancing With The Stars' Maksim Chmerkovskiy and Val Chmerkovskiy, Shenae Grimes, Lord of the Ring's Dominic Monaghan, Hung's Stephen Amell, Matt Dallas, Parenthood's Michael B. Jordan, Greys Anatomy's Jesse Williams, RJ Bergers' Paul Iacono and Jayson Blair, Rachel Zoe Project's Jeremiah Brent, among others.
There was even a live performance by rapper Theophilus London and music by DJ Michelle Pesce.
All were wearing Guess clothing. Needless to say, it was a very fashionable night!
