He explained: "We immediately went home and we reserved all the domain names. We got the Twitter handle, the Instagram - everything you could possibly [have]. I don't want a porn site with my daughter's name! It's unacceptable to me and it's not gonna happen!"
The 36-year-old star also revealed they had already decided on a name before Mila, 31, even got pregnant, but then when they found out they were expecting they went off of their original choice.
Speaking on 'Conan' he explained: "We had another name. We had it picked out and were like, 'All right this is the name'. Then we got pregnant a week - a couple of 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.
"On night, Mila was just like, 'This is not the name!' And I'm like, 'OK! It's not the name'. I had to get the creative juices going."
