(One fifth of) Backstreet's back, alright.

Just days after premiering the nostalgia-filled video for his latest single "19 in 99," Nick Carter hit the stage at the Saban Theatre in Beverly Hills to kick off the All American Tour in support of his latest studio album.

"It’s gonna be a really eclectic and fun show that people are going to enjoy all the way through," he promised PopCrush in a recent interview.

True to his word, the seasoned performer worked his way through hits new and old, including Backstreet Boys classics like "I Want It That Way" and "Show Me The Meaning Of Being Lonely," as well as cuts from his own solo back catalog — and a very special cameo from fellow BSB member, A.J. McLean.
