She may not have given birth to a child in real life yet, but Cameron Diaz now has a better idea how she’ll look as an expectant mother…

Lionsgate has released the character posters for the 39-year-old Cuban American actress’ latest film What to Expect When You’re Expecting, a comedy about dealing with the challenges of impending parenthood.

Based on a screen adaptation of the bestselling book by Heidi Murkoff, the film follows a group of expectant parents whose lives are all somehow intertwined, no matter how different they all may seem.

Along with Diaz, Jennifer Lopez, Elizabeth Banks, Anna Kendrick and Brooklyn Decker form part of the all-star ensemble cast.

All of the characters – except Jennifer Lopez’s, who is adopting – are shown in various stages of pregnancy. A quote from the character is also included, and ranges from the sweets (“I can’t wait to meet my baby.”) to the funny (“If I knew I’d have a rack like this, I would have gotten knocked up years ago.” and the desperate  (“I’m calling bull$#!%. Pregnancy sucks.”)

Many of the quotes on the poster are lines heard in the trailer for the film, which co-stars Chace Crawford, Matthew Morrison, Dennis Quaid, Chris Rock, Rodrigo Santoro, Ben Falcone and Joe Manganiello.

What to Expect When You’re Expecting is set for release on May 11.
