The Backstreet Boys went to Instagram this weekend to celebrate their 26th birthday with a group photo of the old school.
"On this day in 1993, we became the Backstreet Boys," they wrote on Instagram, where they shared a snapshot of their younger singing together on Saturday (April 20).
"From concerts in high school gymnasiums to the world tour this summer (plus a # 1 album !!), we could never have imagined what the last 26 years were going to hold," continues the text. "Thank you all, here are many more years!"
