ASHTON KUTCHER would have been going on Virgin Galactic's next mission to space. But MILA KUNIS stepped in with some reasonable, but downer advice.
Ashton said quote, "When I got married and had kids, my wife basically encouraged that it was not a smart family decision to be heading into space when we have young children." The kids are four and six years old.
So, he ended up selling his ticket back to Virgin Galactic.
But Ashton did say at some point he WILL be going to space . . . I'd guess probably when the kids are older.
