Over and Out! The Year's Biggest Breakups

JENNIFER & MARC

Like their surprise wedding in 2004, Jennifer Lopez and Marc Anthony's split was equally unexpected: The singer and her husband of seven years called it quits in July 2011 – just days before the American Idol judge's 42nd birthday. Though Lopez admitted there's "a lot of work that goes into making a successful partnership and marriage," the Puerto Rican power couple and parents to twins Max and Emme appeared inseparable at June's Hope for Children gala in New York City.
