Gerard Butler: 'Madonna Gave me a Shot in The Bum'

Madonna clearly isn't fazed about giving men injections in the bottom!

At a press conference Thursday for Guy Ritchie's new action flick RocknRolla, actor Gerard Butler revealed, "I got in a B-12 shot in my a-- by..."

"My wife!" Ritchie interrupted.

"Yeah, I got a shot from his wife Madonna!" said Butler. "I was sick, and she was a nurse basically.

"Guy introduced me to her and she said, 'You're the sick one?' and I said, 'Yes,'" Butler recalled.

"Well, she was amazing. She just said, 'Drop your pants,'" Butler added. "I stood there with my little bottom out, and she gave me a shot in the bum!"

But did Madonna make him feel any better? "It didn't work at all — I got more sick!" the actor said. "But I appreciated the effort."
