Brooklyn Decker & Jennifer Lopez: 'Expecting' Stars!

Brooklyn Decker and Jennifer Lopez have signed on to co-star in the upcoming dramedy, What to Expect When You’re Expecting!

The 24-year-old actress and model will play Skyler in one of the film’s interlocking stories, a “perennially perky character, who is married to a much older man [and] sails through her pregnancy with twins much to the consternation of her peers,” according to a press release.

Jennifer, meanwhile, 41, will take on the role of Holly who “adopts a baby from abroad with her husband after difficulty conceiving.”

Cameron Diaz also stars in the film. Sources tell JustJared.com that Matthew Morrison was slated to play her husband but there have been scheduling problems with Glee, though producers are trying to work it out.

What to Expect When You’re Expecting will begin shooting this summer and is slated to hit theaters May 11, 2012!
