This Madonna tidbit from across the pond, in Ananova.

(Adriano) Giannini told the Sunday Express: "It didn't come easy for me to slap a woman, especially someone I had grown up listening to. When I first slapped her, she thought it wasn't violent enough and told me to hit her harder."

"On another occasion, I was asked to humiliate her by making her bark like a dog. It got a bit masochistic but she's good. She's very professional."

M'kay, no surprise there.
