The highly anticipated comedy, hitting theaters on December 18, is about two sisters (Poehler and Fey) who decide to throw one last house party before their parents sell their family home. This includes a series of classic one-liners from the funny girls, incredibly tacky outfits -- is Fey wearing leopard print?! -- and a choreographed dance!
Other familiar faces in the film are Fey and Poehler's pal Maya Rudolph, The Mindy Project's Ike Barinholtz and WWE wrestler John Cena.
Cena -- who also appears in Amy Schumer's comedy Trainwreck-- might have one of the best lines in the trailer. "My safe word is 'keep going,'" he tells Fey's character, Jane Jones, when she hits on him.
On Tuesday, the comedic duo also reunited with fellow Saturday Night Live alum Jimmy Fallon on The Tonight Show. The friends participated in a game of "True Confessions" that got pretty ridiculous.
