Love and Charlize Theron

I read somewhere once (can't remember if this was conjecture or from a printed source) that Courtney Love and Charlize Theron didn't get along on set when they were making this movie. I find it odd because they didn't work together at all aside from the final scene, but I'm wondering if there's any truth to this? Love is obviously not a person that is going to mesh with all personalities, but I wonder what the details are of that if it is in fact true.
