New Kids On The Block have revealed that their joint headlining tour with Backstreet Boys has made them really competitive over their live performances. 

Speaking to BANG Showbiz, NKOTB's Joey McIntyre explained that although it's definitely "friendly competition" having the popular American boyband share their stage on the extensive string of dates motivates them to keep things fresh and exciting and inspires them to be their best at all times:

"It's a shot in the arm. Since getting back with the New Kids in 2008, every time we go out and do a tour, we want it to be fresh and exciting. If we're not excited about it the fans won't enjoy it. And to have another band going at it literally back and forth all night is great inspiration."

"It's not in a 'chip on your shoulder' kind of way, it's more friendly competition. If they go out and do a great set, we want to do it too and vice versa. I'm inspired watching those four guys specifically do their thing but also be individuals."
