Christina "Chrissy" Amphlett, frontwoman for Australian rock band the Divinyls, has passed away at the age of 53. The 'I Touch Myself' singer had been battling multiple sclerosis and breast cancer since 2007, and died at her apartment in New York on Sunday (April 21).

Amphlett's husband, former Divinyls drummer / producer Charley Drayton, confirmed the sad news and spoke fondly of his wife: "Chrissy's light burns so very brightly. Hers was a life of passion and creativity; she always lived it to the fullest... With her force of character and vocal strength she paved the way for strong, sexy, outspoken women... Chrissy was a true pioneer and a treasure to all whose lives her music and spirit touched."

In 1991, the Divinyls scored a No. 4 hit on the Billboard Hot 100 with 'I Touch Myself,' with Amphlett's sultry, libidinous vocals driving the track to the top of the charts. The press release also included that the singer hoped "her worldwide hit 'I Touch Myself' would be utilized to remind all women to perform annual breast examinations."

Rest in peace.
