Cox is an advocate for plastic surgery while Arquette is opposed to cosmetic enhancement, reports contactmusic.com.
The actress said: "If I did that it would be a battle between the two of us. He doesn't like any of that stuff. I think it's easy when you're a boy to say that."
But Arquette insists he'll fight his wife all the way if she ever chooses to have a little plastic surgery. "I like how her smiles make wrinkles," he said.
