The star-studded mother of all ensemble casts attended the What To Expect When You’re Expecting premiere in Los Angeles last night.

Jennifer Lopez dared to go ‘there‘ with her plunging neckline. Seems appropriate, no?

The movie also stars: Cameron Diaz, Elizabeth Banks, Chace Crawford, Anna Kendrick, Brooklyn Decker, Matthew Morrison, Rodrigo Santoro, Ben Falcone, Joe Manganiello, Thomas Lennon, Rebel Wilson, Wendy McLendon-Covey, and Whitney Port — who talked babies, fashion, and more on the black carpet.

Inspired by the perennial New York Times bestseller of the same name, What To Expect When You’re Expecting is a hilarious and heartfelt big-screen comedy about five couples whose intertwined lives are turned upside down by the challenges of impending parenthood.

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?

A kaleidoscopic comedy as universal as it is unpredictable, What To Expect When You’re Expecting finds humor and uplift in all the unexpected trials and triumphs of welcoming a child into the world.
