The Rolling Stones might be one of the headliners at this year’s Coachella Valley Music & Arts Festival based on a few hints that seem to have been dropped by both camps.

The in Indio, California festival’s April 12th date appeared on the band’s official iPhone app in December before being pulled down. Mick Jagger has claimed to know nothing about the Coachella appearance, but a photo on the festival’s Facebook page seems to suggest otherwise.

According to Rolling Stone, The Stones have not played a formal festival gig in the U.S. since Northern California’s Altamont Speedway Festival in 1969.
