All I know is what I read. I don't deny that KR is ever rude and/or moody. I've just never seen a fan siting written that way.
I do remember the interview from the Regis and Kelly show wherein Kelly said she had questions for him from her in-box. Did you see his face and posture stiffen? He said something like, "I can't wait." He was *very* uncomfortable with that idea.(Answering fan mail.)
Personally I would be surprised if he ever went that route.
