“Boy, do these things grow!” she exclaimed to the startled talk show host.
“I don’t know how to deal with them because I’ve never had them. So, I always dress for a flat chested girl and all of a sudden I’m busty and I’m like ‘whoa check it out!’ this is amazing for me! It’s a whole new world,” she added.
Kunis gave birth to a nine-and-a-half pound baby girl, Wyatt Isabelle, last September. The diminutive star, who is five-feet, four-inches tall, gained 25 pounds during her pregnancy.
She credited her quick rebound to exercise and breast feeding, which may also have something to do with her bust size.
Now she says, she has to dress differently. “Well first of all I needed to start wearing bras, that was a whole new experiment for me, like what are these things that people wear?! Now I have to.”
The change in her physical appearance was hard not to notice when she attended the premiere of her new movie “Jupiter Ascending,” in Los Angeles wearing a strapless, Dolce & Gabbana dress that could barely contain her bosom.
She attended the event with co-stars Channing Tatum and Eddie Redmayne. Husband Aston Kutcher was lurking in the wings and dodged the red carpet.
“I saw a red carpet photo of you and Channing Tatum was staring at… he was busted for staring at…um, your breasts,” said Conan as the photo flashed on-screen.
Kunis laughed. “I know him and I love him, and he wasn’t,” she said. “But, boy do these things grow.”
Mila also talked about “hate watching” reality television shows while exercising on a treadmill.
