Jennifer Garner is playing her unborn baby Spanish CDs in the hope the tot will be bilingual.

The actress and her husband Ben Affleck are currently expecting their third child.

Jennifer is said to be eager to give the unborn baby a "head start", so is doing all she can to expose him or her to different languages and cultures.

"She's getting a jump on teaching her unborn baby a second language," a source told National Enquirer. "She hopes that playing Spanish-language CDs will give her baby a head start on being bilingual."

Jennifer and Ben's new arrival is due in February 2012, and will be a sibling for daughters Violet, five, and two-year-old Seraphina.

It's previously been claimed Ben is hoping the tot will be a boy so they can bond over sports.

He even encouraged Jennifer to do certain things said to boost the chances of having a boy before she fell pregnant. He asked his wife to wear men's underwear as much as possible and also cooked her up red meat to feast on.
