Madonna: 'No Nipples' at Super Bowl Halftime Show official

Madonna appeared on last night's Jay Leno Show to promote her new album MDNA as well as to discuss her upcoming performance at the Super Bowl, which she admitted she was nervous about. "It's the most nerve-racking thing I've ever done," the 53-year-old pop sensation admitted. "The Super Bowl is like the Holy of Holies of America, and I have to go on in the middle of that 'Holy of Holies' and put on the greatest show that was ever put on before."
