The Divinyls's song "I Touch Myself" — featured in Prelude to a Kiss and Austin Powers — was a naughty staple of the early '90s. According to TMZ, the band's Australian lead singer, Chrissy Amphlett, died Sunday, April 21 at age 53.

Chrissy was diagnosed with multiple sclerosis in 1998 and revealed she had MS in 2007. In 2011 she revealed she was also battling breast cancer.

Her family released a statement (via Herald Sun), reading in part: "Our beloved Chrissy peacefully made her transition this morning. Christine Joy Amphlett succumbed to the effects of breast cancer and multiple sclerosis, diseases she vigorously fought with exceptional bravery and dignity. She passed gently, in her sleep, surrounded by close friends and family, including husband of fourteen years, musician Charley Drayton, her sister, Leigh, nephew, Matt, and cousin Patricia Thompson."

Last month, she posted a health update on her Facebook page (via the Herald Sun):

"Unfortunately the last 18 months have been a real challenge for me having breast cancer and MS and all the new places that will take you. You become sadly a patient in a world of waiting rooms, waiting sometimes hours for a result or an appointment and you spend a lot time in cold machines like MRI, CT machines,hospital beds,on your knees praying for miracles, operating rooms, tests after tests, looking at healthy people skip down the street like you once did and you took it all for granted and now wish you could do that. ... My illnesses have really exhausted this little body of mine that I have thrown from one end of a stage to another and performed thousands of shows that's sadly some of you missed. With that said I am getting stronger but there is still some fine tuning and work to be done on myself. It's a different self but my voice is strong and not affected by the MS as some reviewers have cruelly reported. I can walk although sometimes I wobble but try to wobble with the beat. I look after myself and my husband has been through this with me every part of the way and I cannot imagine what I would have done without him and his kindness. I did something right."

We hope she's now resting in peace.
