I kind of feel bad for the guy. He was probably talked into it by the people that wanted to do the TV show. In any case, he's bring 6-8 other artists, I'm sure at least one will be a woman. I think he sort of wanted to do this thing where a random stranger would also get to experience this pretty unique voyage.
He's a self-made 44 year old billionaire who works in fashion. I don't think he needs to set-up a tv show and plan a trip to the moon to get a girlfriend.
