Mila Kunis on Baby #2: "I Have No Idea How Far Along I Am!"

The Bad Moms actress dishes all about her current pregnancy. 

Mila Kunis has a confession to make: She's kind of slacking off when it comes to keeping track of her second pregnancy! "With the first one, I literally was on the app every day, like, 'What fruit size is my baby?'" the Bad Moms star confessed on Live with Kelly earlier today. "The other day, someone asked how far along I was and I was like, 'I have no idea. I can tell you when I'm due, and then do the math backward.' With the first one, I could tell you precisely what she was developing, what stage it was. With the second one, I'm running after a toddler, or I'm working, so I'm like, 'Oh, that's right! I'm pregnant.'"

Another difference with this pregnancy? Mila admitted she and husband Ashton Kutcher are having a tough time explaining things to their 21-month-old daughter, Wyatt.

"We were trying to teach Wyatt that she's going to be a big sister and that there's a baby inside Mommy's belly," Mila told Kelly and co-host Keegan-Michael Key. "But she's too little to comprehend that only Mommy's got the baby. So you'll go, 'Where's the baby?' And she'll point to her belly or your belly or your belly. So Ashton's like, 'Oh, that's funny,' so he taught her to be like, 'What's inside Daddy's belly?' And she'll say, 'Beer!' That's my husband, guys!"

Like most moms going through pregnancy a second time, Mila's cravings are also different with baby #2. "With the first one I didn't have any aversions," she said. "[But with] the second one, I can't eat meat. It'll look delicious to me, and I'll take a bite of it, and then I'm like, 'Uh-uh. Can't do it.'"

"But I can eat eggs all day long," she continued. "If someone's like, 'Have an egg for dinner!' I'm like, 'Great.' I can't get enough eggs. It's a very strange pregnancy when it comes to food."
