Backstreet Boys join New Kids on stage

The Backstreet Boys joined New Kids On The Block on stage during a recent performance in New York.

According to Entertainment Tonight, both boybands took the stage at Radio City Music Hall to perform Backstreet Boys hit 'I Want It That Way'.

"I think this is definitely a special collaboration and timing is everything in showbusiness," New Kids member Joey McIntyre said.

Speaking about the Backstreet Boys' fans, New Kid Donnie Wahlberg added: "They have very loyal fans and we have very loyal fans, but I think looking at the few women who were sprinkled around during rehearsal, there was just a look that I haven't seen too often."
