I don't think there is any way those two got together. For one thing, Christine eats twigs like Lindsey for dessert. Secondly, Lindsey has a definite type- petite, blonde, girly, etc. Don't get me wrong... Christine is quite , uh, er, um... very... um... handsome, yeah that's the word.
I know that Christine has tried, and she has done a lot with hair, makeup and clothes. But whenever I see her all made up and wearing a dress, I just see a dude playing dress-up.
She definitely has her own kind of, um, appeal... but definitely not the kind Lindsey would be into.
