Aaron Carter's brother, Nick, sings in which boy band?

Aaron Carter's brother Nick sings in the boy band Backstreet Boys.

Nick Carter joined the group as its youngest member and became one of its lead vocalists. The original lineup also included AJ McLean, Howie Dorough, Brian Littrell, and Kevin Richardson. The group formed in Florida in 1993 and became one of the defining pop acts of the late 1990s and early 2000s.

Nick's connection to Aaron sometimes causes confusion because both brothers had successful music careers. Aaron Carter was a solo pop singer who began performing as a child and later toured with the Backstreet Boys. He also appeared with Nick on the song “Oh Aaron,” which helped link their careers in the public eye.

The Backstreet Boys' major hits include “I Want It That Way,” “Everybody (Backstreet's Back),” and “As Long as You Love Me.” Unlike Aaron, Nick remained a member of the group while also releasing solo albums during breaks in the band's schedule.
