Actress Mila Kunis has poked fun at politically correct dads-to-be in a new Tv skit in which she urges them to stop making pregnancy a couple thing.

The pregnant Ted star filed a public service announcement for future dads on U.S. late night show Jimmy Kimmel Live! in which she took aim at the host when he said, "My wife and I are pregnant."

Kunis, who was sitting in the audience for the show, scolded, "Oh, you're both having a baby? You and your wife are pregnant?"

She then faced the camera and added, "Hi, I'm Mila Kunis, with a very special message for all you soon-to-be fathers... Stop saying 'We're pregnant'. You're not pregnant! Do you have to squeeze a watermelon-sized person out of your lady-hole? No."

As a group of pregnant women walked onstage carrying tubs of ice-cream, Kunis raged, "You're not pregnant. We are."

Kunis' stand for pregnant mums everywhere aired on Jimmy Kimmel Live! on Tuesday night (10Jun14).

The actress is expecting her first child with fiance Ashton Kutcher.
