Madonna discussed her new album and her upcoming Super Bowl halftime performance on NBC's The Tonight Show with Jay Leno on Monday night. She told Jay Leno that the album's title, MDNA, is a "triple entendre." When Leno asked her if it represents both her name and "Madonna DNA," she replied in the affirmative. She then implied that it's also a reference to the drug MDMA, or ecstasy, which provides "euphoric feelings of love."

Looking ahead to Sunday, the queen of pop said the Super Bowl performance will be the "most nerve-racking thing I've ever done," in part because she won't be able to do a sound check beforehand. Calling the Super Bowl "the holy of holies," she joked she has to "put on the greatest show that's ever been put on before, so that's no pressure." Madge promised not to show nipples during the performance because, she quipped, "I don't like to repeat myself or do what other people have done before me," referring to Janet Jackson's infamous wardrobe malfunction.

Madonna did recall her own personal wardrobe malfunction during her iconic performance of "Like a Virgin" at the 1984 MTV Video Music Awards. While wearing a wedding dress and walking down a wedding cake, she said, she lost a shoe, and while trying to recover it, she dove onto the floor, revealing her underpants in the process.

Madonna also plugged her film, "W.E.," which opens in limited release Friday. MDNA drops in March.
