Veteran singer Carly Simon likes to have her bottom spanked before performing live, because it is the best way to conquer her stage fright. The YOU'RE SO VAIN star claims being spanked calms her nerves. However, her unique warm-up was accidentally revealed when she performed at a 1996 concert to mark then-US President Bill Clinton's 50th birthday. Simon says, "The orchestra's horn section all took turns spanking me. But during the spank the curtain went up."
