The Rolling Stones have canceled the night launch of their Australian tour in the wake of the death of frontman Mick Jagger’s longtime girlfriend, L’Wren Scott.

The fashion designer, 49, was found dead in her New York apartment Monday morning.

“The Rolling Stones concert in Perth will not be going ahead as scheduled for Wednesday 19 March 2014,” the group’s site says in a note. “No further information is available at this time, ticket holders are asked to hold on to their tickets until a further update is available.”

Fashion designer L’Wren Scott was found dead of an apparent suicide the morning of March 17 in her New York apartment. She was 47. Scott had been dating Rolling Stones frontman Mick Jagger for more than a decade.
