VIDEOS: Tina Fey and Amy Poehler Double Duty!

SNL Weekend Update former partners Amy Poehler and Tina Fey pulled double duty in both being on The Tonight Show with Jimmy Fallon, and releasing a trailer for their movie that comes out at Christmas called "Sisters," which looks ridiculously hilarious. 

In the movie, the pair play estranged sisters who get upset when they find out their parents were selling their childhood home. The two have a ton of chemistry as celebrity best friends, so these two look like sisters who decide to throw a huge project-x-ish party to send off the house. 

Watch the trailer here:

Now watch the pair on Jimmy Fallon, playing True Confessions:

I honestly love the fact that they are publicly best friends, and they have this awesome relationship with their SNL friends. It makes for watching their appearances with Fallon, Seth Meyers, ect, so much more rewarding. 

Amy Cooper is a writer and pop culture fact nerd, and on multiple occasions has been referred to as a “Walking iPod.”
