Gary Allan's wife, Angela Herzberg, died early Monday morning (Oct. 25) of a self-inflicted gunshot, his record label confirms.

No other official details are immediately available, but the shooting reportedly occurred in the Nashville suburb of Hendersonville, Tenn. Allan and Herzberg, 36, have six children and moved to Tennessee from California in 2003.

Allan immediately cancelled a series of tour dates, including shows this week in Portland, Maine, Uncasville, Conn., and Burgettstown, Pa.
