Kelly Clarkson will be heading to Nikon at Jones Beach Theater on Aug. 21, co-headlining with The Fray.

The original “American Idol” will hit the road on July 21, after her mentoring duties on “The Voice” are finished and presumably after she's done mentoring on the new ABC show “Duets,” which launches on May 24. Clarkson will be promoting her album “Stronger” and the third single “Dark Side,” the follow-up to the No. 1 title track.

Tickets go on sale at 10 a.m. Friday through Live Nation.

Carolina Liar is set to open for Clarkson and The Fray, who are supporting their “Scars & Stories” album.
