Details are sketchy, but Williams' band will begin rehearsing for the outing on September 2, touring guitarist Roger Dorsey said in a chat Saturday (7/21) night on the group's Web site.
"We don't have an exact date for the tour yet, but it's supposed to start in October," Dorsey said. A Jive Records spokesperson said the dates are still being finalized.
The pop superstar will not join the group for the initial rehearsals, bassist Freddy Mollings said in the chat. "She'll be working on the dance moves first, before we see her. She probably will pop in a little later while we learn the songs."
Williams' band has not heard the new record, which hits stores August 14 and features production from the Neptunes and Jermaine Dupri.
