It's official—Ashton Kutcher is an awesome dad.
The Two and A Half Men star took over baby duties last night while Wyatt Isabelle's mom Mila Kunis was walking her first red carpet since giving birth to their daughter four months ago.
"He just put the baby down to sleep," Kunis said at the premiere of Jupiter Ascending, her new sci-fi flick with Channing Tatum and Eddie Redmayne. "He's taking an Uber here."
Really? He Uber-ed to the premiere?
"We're very normal," Kunis explained. (Kutcher also happens to be an investor in the car service.)
The first-time mom looked gorgeous in a black Dolce & Gabbana cocktail dress and Gemfields ruby jewelry by Miiori.
"Let me tell you, having a baby and breastfeeding—nothing fits in these dresses anymore," Kunis said while cupping her bosom with both hands. "This is hard off a runway."
Kunis, who continued to fuel rumors that she and Kutcher secretly married by wearing a band of diamonds on her wedding finger, admitted she wasn't sure how quickly she'd be returning to work.
When I asked if she's ready for her next project or is happy just being at home with Wyatt, Kunis said, "I'm figuring it out."
In Jupiter Ascending, Kunis plays Jupiter Jones, a cleaning lady who learns that she is the queen of the universe. Tatum is a half-wolf warrior from another planet that is charged with finding her and bringing her back to his planet to end the reign of an evil tyrant (Redmayne) determined to have Jupiter killed.
Kunis said she did all her own stunt work in the action-packed sci-fi flick.
"Hanging on a wire 17 hours a day for eight months gets exhausting," she said.
Harder than being a new mom?
"Hanging on a wire for 17 hours a day is way more exhausting because it's 17 hours, you don't sleep, you're bruised. You feel tired," she explained.
Not that a newborn can't be just as tiring. "But you have a baby," Kunis said. "You have a little being. There's nothing to have there, you're just killing yourself and you don't know what the final product is. Here, I have the final product in front of me."
Jupiter Ascending is in theaters on Feb. 6.
