Actually I thought about this after posting, and decided I had a more pressing reason to warn men off her. You've given me an excuse to revisit it!
It's mostly down to her having sex with Billy Bob Thornton. He just
looks dirty. Dirty as in a bit grubby, as well as all the rest. I wouldn't touch someone BBT had slept with, with a stick. Unless it was John Barrowman, and sadly he is strictly a one way street - in the opposite direction.
