Celebrity Boy Band Fans: From BTS Army to Directioners and BSB Diehards

Whether they pledge allegiance to the BTS Army or belong to the official New Edition fan club, there are plenty of celebrity boy band fans in Hollywood. No one, not even movie stars, can resist the appeal of a three-part harmony and a catchy hook.

The phenomenon encompasses celebs of all ages, from Selena Gomez, who was a mere tween during 'NSync's heyday, to John Cena, who has been a legal adult for the entirety of BTS' reign.

"I'm a fan of BTS," the former wrestler said during a January 2020 appearance on The Late Late Show With James Corden. "I became interested in the fact that they're a Korean pop band and they were the first Korean pop band to actually connect everybody throughout the world. ... Then I began to listen to their music and listen to the message they send to their fans, and it's one of self-love and self-reflection and being confident in yourself even though you may be different."

BTS, however, isn't the only boy band out there with a celebrity following. The Backstreet Boys, who got their start in 1993, count Blake Lively and Joe Manganiello among their fans, while Boyz II Men is beloved by Monica and Dianna Agron.
