Pictures of Celebrities at the HBO Emmy Awards After Party: Olivia Munn, Lucy Liu and more!

Yesterday's frock-fest didn't end with the red-carpet. There was the stylish after-party crew, too! Joining the fun, we spotted a few surprise appearances, like Chloë Sevigny in a party-appropriate LBD and Entourage alum Emmanuelle Chriqui taking the sexy approach in a slitted, strapless gown. Ashlee Simpson made an entrance in a vintage-feeling, embellished gown along with The Newsroom's sexiest reporter, aka Olivia Munn, solidifying her sultry status in Armani Privé Couture, while Lucy Liu did a Versace change-up, trading her metallic version for the label's powder-blue, rivet-studded strapless.
