Backstreet Boys celebrate 25 years together with a flashback photo

The Backstreet Boys took to Twitter on Friday to celebrate a very special anniversary for the boy band – 25 years! “On April 20th, 1993 we became the Backstreet Boys,” the group captioned an adorable throwback photo. “If you would have told us that 25 years later we would still be making music together, we would have never believed you. Thank you #BSBArmy Who’s ready for another 25 years? #KTBSPA#BSB25.”
