Backstreet's back, all right!

Founding member Kevin Richardson is officially returning to the Backstreet Boys, the group announced on its Twitter account Sunday.

"Now everything is back to normal ... welcome back Kevin Richardson," the boy band tweeted.

Richardson left the Backstreet Boys in 2006 to pursue other interests. The singer has made occasional appearances with the group since his departure.

Richardson and the rest of the group will soon be headed back into the studio to record a new album.
