Ashton Kutcheris moving mountains for his wifeMila Kunis— well, at least trying to name one after her!
The 45-year-old actor talked about the romantic gesture while promoting his new film,Your Place or Mine, on Monday’s episode ofThe Late Late Show with James Corden.
Discussing a trip to the South Pole he once tookto help with an autoimmune condition, Kutcher said he met a man who asked if he wanted to climb a mountain, to which he agreed.
“We get to the top and he said, ‘You’re the first person that has ever climbed this mountain. You get to name it,’ " he recalled to hostJames Corden. “I was like, ‘Okay really? It’s Mount Mila.’ And he says ‘No, no, it’s bad luck to name it after another person, so don’t do that.’ "
Kutcher shifted gears and named it"Awesome” in Russian. Kunis, 39, was born in the Ukraine and grew up speaking Russian.
“So I got to name a mountain while I was there,” the entrepreneur added. “It was wild.”

Expanding on what brought him to Antarctica in the first place, Kutcher further discussed his health.
“Ihad a weird autoimmune disorderthree years ago,” he said. “So last year, I was like, ‘I am just going to push myself to the end of my physical capacity in every form.’ "
“I went to the South Pole, Iran a marathon, I wentRunning Wild with Bear Grylls,” the former model continued to Corden, 44, of his personal mental and physical journey. “I was just going to push it as far as I can just to get the self-confidence that I’m fully back, which I am.”
