When asked by New York radio station Z100 if a tour is on the horizon, the popstar said: "Oh definitely, next year. Around the world."
Spears's last album Blackout was released in November of last year, but the singer did not go on the road to promote it.
The Circus tour will be her first since 2004, although she performed several club shows in California recently under the pseudonym M+M's.
Circus is scheduled to be released on December 2, Spears's 27th birthday.
