The Backstreet Boys Have Some Advice For One Direction

After 22 years in the biz, the most successful boy band in the world have a few pearls of wisdom for young chart-toppers, One Direction.

Speaking exclusively to MTV, the Backstreet Boys advised Harry, Zayn, Liam et al to "just have fun" (not a problem) and always remember to appreciate the people who are responsible for their success - the fans.

Brian, Nick, AJ, Kevin and Howie went on to discuss how difficult being in an internationally famous pop group can be - and how easy it is to get on each other's nerves. AWKS!
