Rihanna, Big Sean, Cassie + More Attend GQ’s Men of the Year Party

In wake of PEOPLE naming Channing Tatum as their Sexiest Man Alive, GQ magazine also feted the human of the male persuasion with its annual GQ Men of the Year Awards (and party!) in Los Angeles yesterday (Nov. 13). And who wouldn't want to be surrounded by all of those delicious looking men... in suits!

The event was held at L.A. hotspot Chateau Marmont and it drew quite the star studded crowd. Not only were Rihanna, Big Sean, Cassie, and more artists in attendance, but actors like the aforementioned Tatum, Ben Affleck, and Zachary Quinto came to "pay their respects" to the men.

Rihanna was the only woman to be honored at the typically all-male event. The workers and editors at GQ nominated the singer and officially branded her 2012's Obsession of the Year. Okay, now we wish we had that honor bestowed upon us in a room full of some of the must beautiful men around!
