John Legend's moniker wasn't always so legendary. In fact, it took a legal contract to secure the right to even use his now-popular stage name. "J. [Ivy] heard me singing, playing and doing all I was doing on those College Dropout tracks [with Kanye West], and he was impressed," Legend, 46, recalled of his musical origins in Amazon's Word+Music docuseries, per People. "He said, 'Man, we're gonna have to call you the legend.'" Legend (born John Stephens) soon decided to go by his newfound nickname professionally.
