The 3rd Annual Governors Awards, hosted by the Academy of Motion Picture Arts and Sciences, was held this Saturday in L.A. at the Hollywood & Highland Grand Ballroom.

Celebs suited up in their best duds — meaning bowties for the guys and formal gowns for the girls.

Notoriously laidback actor Woody Harrelson skipped the bowtie but added a pop of color to the event in his blue button-up.

Though, Knocked Up's Seth Rogen, also known for his casual style, looked perfectly geek-chic in his glasses and tux.

Also in attendance were John Travolta, Kelly Preston, Alec Baldwin, Maria Shriver, Melissa McCarthyOctavia Spencer, Sharon Stone, Tilda Swinton, Gary Oldman, Evan Rachel Wood and Sidney Poitier.
