Kevin Richardson is leaving Backstreet Boys, the popular 90s boyband to pursue his own interest, as said on their official website.

Backstreet Boys is the only boyband that I ever like, the guys are cool and their songs are great. During my high school days we always try to dance a bit like the Backstreet Boys.
It’s kinda sad to see Kevin leaving, they just produced an album “Never Gone” in 2005 and I thought the Backstreet Boys are back again.
No plans on recruiting new members at the moment, the remaining 4 members The remaining members, AJ McLean, Nick Carter, Howie Dorough, and Brian Littrell will continue their band journey and will be recording a new album soon.
The boys seperated with Kevin in peace and will always welcome back Kevin.
Btw, Kevin is the 2nd on our left in the above album cover pic.
