Lionsgate film also stars Cameron Diaz and Jennifer Lopez
Brooklyn Decker is joining the pregnancy comedy "What to Expect When You Are Expecting," Lionsgate announced on Thursday.
The model and actress is best known for strutting around in a swimsuit, but she is branching out into the film world.
She narrowly missed playing the female lead in "Transformers: Dark of the Moon," and is slated to appear in Universal's tentpole film "Battleship."
"What to Expect," the famous pregnancy advice book, is being turned somewhat improbably into a romantic comedy.
Kirk Jones ("Nanny McPhee") will direct.
