For some truly unfathomable reason, Arthur and White were never as close as their characters Dorothy and Rose. It makes no sense, and yet, this is one feud that has unfortunately never been fully debunked. (That said, the intensity of their dysfunction does vary depending on who's telling the story.)
Rue McClanahan once revealed in an interview that she had her own issues with Arthur too. "Bea and I didn't have a lot of relationship going on," McClanahan said. "Bea is a very, very eccentric woman. She wouldn't go to lunch [with me] unless Betty [White] would go with her."
