What happens to mean girls when they grow up? Ask Bachelorette's Regan (Kirsten Dunst), Katie (Isla Fisher) and Gena (Lizzy Caplan), a longtime group of friends who are instantly embittered when they find out their fourth wheel, Becky (Rebel Wilson), has gotten engaged. Though it's clear that Regan is overcome with jealousy, she pledges to throw Becky a smashing bachelorette party. Unfortunately, the girls become more focused on recapturing their glory days than showing Becky a good time.
There are so many things I love about this trailer. First of all, Kirsten Dunst's face when Becky tells her she's gotten engaged is priceless. Second, I've never seen Rebel Wilson in a role that I didn't enjoy and though it looks like she's playing a bit of a straighter character than she did in last year's Bridesmaids, I'm still looking forward to watching her. And third, Lizzy Caplan and Adam Scott together again? Can you say Party Down reunion? Watch the trailer after the jump.
