Britney Spears demonstrated her fake British accent during her concert at London's O2 Arena on Friday.
E! News reports that the 36-year-old pop superstar was having different sections of the audience compete to see who could scream the loudest.
"Are you guys ready? Do you think you can do this?" she yelled in her faux-English accent. "One, two, three!"
She also jokingly scolded them, "What the hell is wrong with you? You've got to do better than that. Let's try it again."
