Cue the one liners!

Hollywood's hottest showed up for tonight's annual White House Correspondents' Dinner, hosted by funnyman Conan O'Brien, and the A-lister's didn't disappoint with their fashion, captured first on E!'s exclusive livestream from the red carpet.

Stars including Kerry Washington, Katy Perry, Claire Danes, Connie Britton, Rebel Wilson and Darren Criss stunned as they made their way into the dinner.

Kerry donned a black and white ensemble while Rebel opted for a navy look. But it wasn't all dark shades, as Chrissy Teigen sizzled in sparkles along with Olympic gymnast Gabby Douglas, while Nashville star Hayden Panettiere rocked a strapless yellow getup.

Even Katy Perry gave her crop tops a rest and glammed it up, choosing a green strapless floor length gown.

As for the men? Darren looked dashing in a tux, along with Scandal's president Fitz, Tony Goldwyn.

And let's not forget Michelle Obama's fashion. FLOTUS stunned in a Monique Lhuillier black fitted draped chiffon goddess-like gown with high neckline in delicate Chantilly lace.

Take a look at all the pics below. And for more from the White House Correspondents' Dinner, tune in to E! News Monday at 7 p.m. and 11:30 p.m.
