Mila Kunis insists she doesn't mind working while she's pregnant.

The actress, who is expecting her first child with fiance Ashton Kutcher in October, is currently promoting the new movie, but admits it will probably be harder to manage everything once their baby is born.

Asked if it's difficult for her to be doing interviews and attending red carpet events, Kunis told US chat show host Jimmy Kimmel: "It's fine. It's really fine."

The presenter, who is also expecting his first child with wife Molly McNearney, predicted things will be tougher to juggle when Kunis and Kutcher's baby arrives, and she replied: "Yeah."

The brunette beauty then poked fun at Kimmel, Kutcher and other fathers-to-be by spoofing a public service announcement, warning men never to say they're pregnant too.

When Kimmel said: "We are having a baby very soon, as well," the Kunis sarcastically asked: "Oh, you're both having a baby? You and your wife are pregnant?"

She then jumped out of her seat, grabbed a microphone and said: "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."

She also lamented the fact she couldn't drink tequila, before being joined by a group of pregnant women holding tubs of chocolate ice-cream at the end of the sketch, and added: "You're not pregnant. We are."
