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.
