Over 18 recognizable faces fill the screen during the course of 'New Year's Eve,' but the stars that didn't get invited to that party shouldn't feel too slighted -- they probably just wound up in 'What to Expect When You're Expecting.' The next omnibus romcom debuted its first trailer on Thursday night, and it features everything from Chris Rock wearing a Baby Bjorn to Cameron Diaz affecting some crazypants accent. Also, Melissa McCarthy's husband, Ben Falcone! Air Marshall Jon, y'all! Watch above.
