(AP) — Brooks & Dunn are done.

The best-selling country duo posted a message on its Web site Monday saying they’ve agreed to “call it a day” after 20 years of making music together.

“This ride has been everything and more than we could ever have dreamed … We owe it all to you, the fans,” Kix Brooks and Ronnie Dunn said in the message. “If you hear rumors, don’t believe them, it’s just time.”

Brooks & Dunn will release a greatest-hits album on Sept. 8 and tour one last time in 2010.
