Anna Kendrick and Brittany Snow reunited with a bunch of their "Pitch Perfect" costars Friday in New Orleans ... all for a pretty awesome "Moulin Rouge" themed wedding party.
Anna and Brittany hung out at Lucky Pierre's for their friend Courtney Barnes' pre-wedding bash with Kelley Jakle and CJ Perry -- more famously known as WWE Diva Lana -- as well as a few Trebles.
We're told the group rented out the Bourbon Street joint for $7K and dined on gumbo.
Unclear if they did any mermaid dancing.
