The "She Sells Sanctuary" singer, 50, and Black Ryder singer/guitarist Aimee Nash "were married on Saturday afternoon, May 26, at the Little Church of the West," his band's rep confirms to PEOPLE.
The couple tied the knot before The Cult's concert at M Resort in Las Vegas that same night.
A source says they met when Nash's band opened for The Cult in Australia and that they had been engaged for several months.
The Cult just kicked off a U.S. tour in support of new album Choice of Weapon.
