Who knew Jelly Roll had some boy-band in him? The singer was playing History in Toronto Wednesday night when he called Backstreet Boys member AJ McLean on stage for a surprise duet of the band's 1999 hit "I Want It That Way." After the concert, McLean shared a photo to his Instagram Story of himself and Jelly posing together. "What a night last night," he wrote, tagging the Jelly. "Let's make some music brotha!"
