Mila Kunis says life since the birth of her daughter is “a whole new world.” To be clear, she’s talking about her breasts.

When she visited Conan on Wednesday, host Conan O’Brien ribbed Kunis’s Jupiter Ascending costar Channing Tatum for apparently checking out her chest in a picture from Monday’s premiere.

Four months after Kunis, 31, gave birth to her daughter Wyatt with husband Ashton Kutcher, the star had a simple defense: “I know [Channing], and I love him. He really wasn’t. But boy did these things grow!”

Though she let Tatum off the hook this time, she did say that “Men actually look at my boobs – I’ve never had that happen before – because they’re just there.”

She admitted, “I don’t know how to deal with them because I’ve never had them, and so I always dress for a flat-chested girl and now all of a sudden I’m busty, and I’m like, ‘Wow, check it out!’ This is amazing to me. It’s a whole new world!”

The biggest style change? “First of all, I needed to start wearing bras,” said Kunis. “That was a whole new experiment for me.”
