Never thought we'd see these two partying together! Denise Richards and Ashlee Simpson's ex Pete Wentz celebrated National Walk Of Shame Day.

We're told the twosome, and a slew of other partygoers, enjoyed Svedka's all-new specialty cocktails, the "Badge Of Honor" and the "All-Nighter." What a great way to loosen up while discussing your scandalous "Walk of Shame" stories. Delish!

Guests also received Svedka's Walk of Shame After Party Pack which included lip balm, sunglasses, dry shampoo, deodorant, breath mints and sweetspot cleansing wipes. Gotta stay fresh!

Find out which former couple were also photographed chatting away ... after the jump.
