Jennifer Lopez to Star in 'What to Expect'

Jennifer Lopez is joining the cast of What To Expect When You're Expecting, the film adaptation of the book that has dominated best-seller lists for more than 500 weeks. She will star with Cameron Diaz in the movie, which Lionsgate says is expected to begin shooting next month for a Mother's Day Weekend release in 2012.



How is that book - which is a guide to pregnancy - going to be turned into a movie? Lopez will play Holly in one of the film's the interlocking stories. The character is a woman who adopts a baby from abroad with her husband after having difficulty conceiving.
