WATCH: Mila Kunis Talks Baby Daughter Wyatt, Weight Loss and Breastfeeding

Mila Kunis hit the red carpet for the first time as a new mommy earlier this week, attending the premiere of her movie Jupiter Ascending with Channing Tatum.

However, while most new moms are anxious to get some freedom after the first few months of motherhood, Kunis admitted she cried when she had to leave her newborn baby daughter Wyatt behind.

“It’s really weird to be out,” Kunis confessed on Jimmy Kimmel Live! Tuesday. “This is my very first time out and about. Swear to God! I left her at home yesterday for the first time during the premiere. It’s frightening. I have to be honest because I was with her every day for the first four months, every day of her little life. I cried. I did. It’s weird. It’s very strange. If anyone’s a mom, and being a stay-at-home mom, it’s a very weird feeling to all of a sudden leave your child.”

Of course Kimmel couldn’t help but joke about whether or not Kunis — who was wearing her go-to Marina B by Gemfields emerald ring and Nina Runsdorf by Gemfields emerald earrings — trusts her fiancé Ashton Kutcher with their daughter.

“I trust him! He’s an incredible father! But the way that I hold the baby and the way that he holds the baby, I mean, he’s like a jungle gym… It’s frightening!”

Meanwhile, Kimmel also brought up the fact everyone has been talking about this week: her “impressive” weight loss just four months after giving birth.

“Breastfeeding is like working out,” Kunis joked before commenting on a more serious note, “I am very active. I hike almost every day with her… I strap her in a papoose and away we go.”
