A new trailer for the star-filled feature version of What to Expect When You’re Expecting has arrived. When a trailer begins with the voiceover, “Having a baby can be a real mother,” it can only go uphill. The movie is essentially Valentine’s Day with babies, as we see a bunch of famous people deal with the ups and downs of pregnancy. Chris Rock and Rob Heubel continue to be the highlights of the footage, and this trailer inexplicably gets rid of all the female characters halfway through. I’m no expert, but I’m fairly certain that ladies are a vital necessity for the production of little humans.

Hit the jump to watch the trailer. The cast also includes Anna Kendrick, Cameron Diaz, Dennis Quaid, Jennifer Lopez, Rodrigo Santoro, Joe Manganiello, Chace Crawford, Matthew Morrison, Brooklyn Decker, Thomas Lennon, and Wendy McLendon-Covey. What to Expect When You’re Expecting opens on May 12th.

Here’s the synopsis for What to Expect When You’re Expecting:

Over the moon about starting a family, TV fitness guru Jules and dance show star Evan find that their high-octane celebrity lives don’t stand a chance against the surprise demands of pregnancy. Baby-crazy author and advocate Wendy gets a taste of her own militant mommy advice when pregnancy hormones ravage her body; while Wendy’s husband, Gary, struggles not to be outdone by his competitive alpha-Dad, who’s expecting twins with his much younger trophy wife, Skyler. Photographer Holly is prepared to travel the globe to adopt a child, but her husband Alex isn’t so sure, and tries to quiet his panic by attending a “dudes” support group, where new fathers get to tell it like it really is. And rival food truck chefs Rosie and Marco’s surprise hook-up results in an unexpected quandary: what to do when your first child comes before your first date?
