Whether it's true or not, I don't blame Elisabeth for making those comments. Let's say that it's all lies - that she hates working with Rosie, and does cry all the time. What good would it do for her or the show to confirm that? Or to refuse to deny it? She could say nothing, but then the questions are going to keep coming. By making the statements she has, true or not, she puts an end to it. If they're true, that's that. If they're not, then she's taken the high ground by letting it be known she's not going to get into a public spat with Rosie.
