The Two and a Half Men star has signed up to be the 500th "astronaut customer" that will blast into space aboard Virgin Galactic.

"I gave Ashton a quick call to congratulate and welcome him. He is as thrilled as we are at the prospect of being among the first to cross the final frontier (and back!) with us and to experience the magic of space for himself," Virgin CEO Richard Branson announced on his blog Monday. The date of Kutcher's flight has yet to be announced.

It is estimated that tickets for the trip cost around $200,000. Pricey! If recent reports claiming Demi wants Ashton back are true, we wouldn't be shocked if the 49-year-old actress suddenly takes up an interest in space exploration!
