It was only a matter of time before AJ McLean danced to a Backstreet Boys song on Dancing With the Stars, and he didn't disappoint. On Monday night, the singer danced the cha-cha to BSB's 1999 hit "Larger Than Life." For the special number, he had the help of his bandmates as they joined him virtually on stage. As McLean noted on the show, this is the first time the band has performed together in six months. They previously made an appearance on the iHeartRadio Living Room Concert in March. Wearing a flashy red outfit, McLean was completely in his element as he danced alongside his partner Cheryl Burke on the ballroom floor. Watch the fun performance above!
