Ashton Kutcher is one of those names that sounds like it comes from the Golden Age of Hollywood, when leading men had names like 'Rock Hudson', intended to make them sound rugged, macho and tough. But Kutcher isn't a throwback to that era; he's just using most of the parts of his real birth name.
The actor, serial investor, and husband of actress Mila Kunis, made a startling admission when he was on stage at the Teen Choice Awards in 2013. His full name is actually Christopher Ashton Kutcher. There was a surprised scream from the audience. He just doesn't look like a 'Christopher' at all, and you can't imagine anybody calling him by that name! It isn't clear when or why the first name disappeared from Kutcher's life, but I think we can all agree that we're glad it did.
