Madonna vs. Lady Gaga (with help from Elton John)
At a May 31 concert in Tel Aviv, Madonna performed a mash-up of her 1980s hit "Express Yourself" and Lady Gaga's "Born This Way." Gaga responded to Madonna for stirring up the "haterade" at a concert in New Zealand: "It sometimes makes people feel better about themselves, to put other people down, or make fun of them, or maybe make mockery of their work, and that doesn't make me feel good at all." The feud began in January when Madonna dissed Lady Gaga's sort of-sound-alike track and described it as "reductive" to ABC News' Cynthia McFadden. By summer, Elton John had entered the fray, complaining about Madonna's treatment of Gaga. "She's been so horrible to Gaga," he said referring to his son's godmother. Then he took his own swipe at her, telling an Australian TV show in August that not only was Madonna's career "over," but that she looked like a "fairground stripper."
