Madonna’s ‘Swept Away’ co-star Adriano Giannini was stunned when the Material Girl asked him to hit her harder in a scene while filming.

“When I first slapped her, she thought it wasn’t violent enough and told me to hit her harder” he said. “On another occasion I was asked to humiliate her by making her bark like a dog.”

“Seriously, it got a bit masochistic, you know but she seemed to love it and was very professional.”
