All five members of the Backstreet Boys will perform during the U.S. group's "In a World Like This" summer concert tour.
Tickets are to go on sale Friday.
Jesse McCartney and DJ Pauly D are to be guest performers on the tour.
"Backstreet Boys are going on tour this summer," Carter said on Ryan Seacrest's website Monday. "That's right, baby! All five of us are back together. It's our 20th anniversary tour. We've got a brand new album coming out."
