The 'Jupiter Ascending' star - who gave birth to her and partner Ashton Kutcher's daughter Wyatt in October - admitted its taking time to get used to her curvy post-pregnancy body as the formerly "flat-chested" star has started receiving attention over her cleavage.

She told Conan O'Brien on his talk show 'Conan' last night (04.02.15): "I don't know how to deal with them, because I've never had them.

"I always dressed for a flat-chested girl, and all of a sudden I'm busty... This is amazing to me. It's like a whole new world.

"Men actually look at my boobs! I've never had that before."

However, the actress was quick to defend Ashton, 36, when presented with a photograph of him appearing to sneak a peak down her stunning black Dolce & Gabbana cocktail dress at the Los Angeles premiere of 'Jupiter Ascending' on Monday night (02.02.15).

When Conan alleged that the 'Two and a Half Man' star had been distracted by her breasts, Mila joked: "He really wasn't. But boy do these things grow."

The brunette beauty recently confessed it has taken time to get used to her new body after finding that "nothing fits" her straight off the runway anymore.

The petite star explained: "Let me tell you, having a baby and breastfeeding - nothing fits in these dresses anymore. This is hard off a runway."
