"Super Soaker" will be the lead single to the September release.

Kings of Leon will return this fall with its sixth studio album: "Mechanical Bull" is due out Sept. 24 on RCA Records. The group was primed to announce the new album during its headlining performance at New York's Governors Ball Music Festival on Friday night (June 7), but inclement weather prevented the band from taking the stage; however, sources have confirmed the album title and release date to Billboard.

The first single is reportedly titled "Super Soaker" and will be released in mid-July. The group reportedly finished recording the album with longtime producer Angelo Petraglia in March, after starting in on the project last fall.

"Mechanical Bull" follows 2010's "Come Around Sundown," which has sold 727,000 copies to date, according to Nielsen SoundScan. The Southern rock group's 2008 breakout full-length, "Only By The Night," has sold 2.3 million copies and spawned the smash hit "Use Somebody," which won the Grammy Award for Record of the Year in 2010.

An onstage meltdown by singer Caleb Followill during a July 2011 performance in Dallas forced Kings of Leon to scrap the remainder of its U.S. tour. However, the quartet has scheduled a slew of dates for 2013, including appearances at the U.K.'s V Festival and at Austin City Limits Music Festival.
