Well, the word on the street - and I am wearing a Mackintosh right now - is that Routh had a MySpace account (cos before Superman he was pretty much an unknown, like Hugh Jackman before Wolverine) which openly stated he was gay. Then he gets cast as Superman, the account is pulled and now he has a girlfriend. Hmm.
No, Spacey hasn't been married, but he DID take his mum to the Oscars.
Even if he had, Elton John's been married before!
DISCLAIMER: Not that it matters, of course. The whole gay thing.
