JC Chasez
After winning a national dance competition at 13, JC Chasez earned a spot on "The Mickey Mouse Club," which is where he first met future bandmate Justin Timberlake. He became one of the five members of mega-popular boy band 'N Sync in 1996. After making a splash in Europe's pop scene, the group brought their self-titled debut with singles "I Want You Back" and "Tearin' Up My Heart" to America and America fell hard. Their next album No Strings Attached was the best-selling album of 2000 and contained the Grammy-nominated "Bye Bye Bye." After selling more than 40 million CDs worldwide and releasing their fourth album Celebrity in 2001, the quintet split up. Chasez released his first solo project, Schizophrenic, in 2004. The first single "Blowin' Me Up (With Her Love)" enjoyed some chart success thanks to its inclusion on the "Drumline" soundtrack and accompanying video featuring his then girlfriend Tara Reid and his mullet experiment. But he has spent the years since 'N Sync disbanded writing songs for other acts including the Backstreet Boys and David Archuleta as well as judging several seasons of "America's Best Dance Crew" on MTV. In 2013, Eva Longoria's ex announced he's assembling an all-female group, Girl Radical.
