This is so funny, I literally have watched this video 20 times. Charlie Puth was a guest on the Zach Sang Show and he was talking not just about his career and new music, but he had a moment where he spoke about The Backstreet Boys, which by the way are going to be at this years Y100's Jingle Ball on December 18th! He said that on the song "The Call" by the BSB, there is a hidden FART in the song! Literally someone let it rip during the recording and they decided to keep in. At first someone could be like, yea right, but AJ McLean did his own duet to the video on TikTok confirming that this is true!
Let's see if below you can hear it in the song.
