Soon-to-be dads, listen up: don't even think about uttering the phrase, "We're pregnant" - because, as Mila Kunis so succinctly puts it: "Do you have to squeeze a watermelon-sized person out of your lady-hole? No."

The 30-year-old actress, who is expecting her first child with fiancé Ashton Kutcher, got her rant on about those three potent words in a hilarious appearance on Jimmy Kimmel Live! this week.

Host and fellow expectant parent Jimmy Kimmel kicked off the tirade, by saying: "My wife and I are pregnant... We are having a baby very soon as well."

To which Kunis narrowed her eyes and replied sarcastically: "Oh, you're both are having a baby? You and your wife are pregnant?"

She then pretended to storm off before grabbing a mic and taking to the stage for her pointed diatribe:
