Ashton Kutcher visited Conan O'Brien last night and answered the question that's surely been keeping you up nights: How did he and Mila Kunis decide on a name for their new daughter? Well, "We had another name picked out and we're like, 'Alright, this is the name," Kutcher explained on Conan, as OK! magazine reports. "Then we got pregnant a week—a couple weeks after we picked the name. But then when we were pregnant, the name just didn’t fit the energy that we were feeling. We were calling it 'the baby,' but never by the name that we had given it. One night Mila was just like, 'This is not the name!' I’m like, 'OK! It's not the name.' I had to get the creative juices going."
"We were going to a Lakers game and I've got name Tourette's," he continued. "I just started listing off anything and everything that I saw. I was like, 'Sign! Truck! Wall! Door!' She's like, 'Shut up!' I’m like, 'If you don’t accept my bad ideas, you’ll never accept the good ones.' Then I was like, 'Alright I've got a really dumb idea. What about Wyatt?' She goes, 'That's it.' I was like, 'Really? I did it?' She was like, 'Yeah, that’s it.'" As for the baby's middle name, as People reports, Kutcher explained that "We gave her the name Isabelle after Mila’s grandfather, who was Yitzhak. And so it has a little heritage." But don't even think about registering wyattisabelle.com for nefarious purposes: Kutcher and Kunis already reserved possible domain names, because "I don’t want a porn site with my daughter’s name," said Kutcher.
