Mila Kunis and Ashton Kutcher

Ashton Kutcher and Mila Kunis named their baby at a basketball game.

The 'Two and a Half Men' star - who had baby Wyatt Isabelle with fiance Mila last month - has revealed that they chose the name whilst watching the Los Angeles Lakers play.

Speaking on 'Conan', Ashton said: "We were going to a Lakers game and I've got name Tourette's.

"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.'"

Ashton also revealed that the couple gave the baby Isabelle as a middle name after being inspired by Mila's grandfather, Yitzhak.

"It has a little heritage," he added.

Meanwhile, the 36-year-old actor also revealed that the pair had a name picked out before they even found out they were expecting a baby but ditched it because the "energy" didn't feel right.

He explained: "We had another name picked out and we're like, 'Alright, this is the name.

"Then we got pregnant ... 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."
