Another day, another casting announcement from the star-studded film adaptation of What to Expect When You’re Expecting. Lionsgate has confirmed that Dennis Quaid will pair up with Brooklyn Decker in the ensemble comedy, for a May-December romance that hits a speed bump when Quaid’s character, Ramsey, learns that Decker is pregnant with twins. In a Duggar family style twist, Ramsey’s son Colin is also expecting his first child, and the competitive Ramsey is determined to one-up his son.

Quaid’s is the latest name added to the film’s roster, but the big screen version of Heidi Murkoff’s pregnancy guide is certainly not hurting for stars. Cameron Diaz, Jennifer Lopez, Elizabeth Banks, Anna Kendrick, Chace Crawford, Rebel Wilson (Bridesmaids), Glee‘s Matthew Morrison, and True Blood‘s dreamy Joe Manganiello have already signed on. Filming is set to begin this month for a scheduled May 11, 2012 release.
