Cult rocker Kim Gordon has suggested another woman was to blame for her split from her husband and Sonic Youth bandmate Thurston Moore.

The indie rock stars, who wed in 1984, stunned fans when they announced the end of their marriage back in October 2011, and Gordon has now opened up about the split in a candid new interview, in which she appears to confirm her husband had an affair.

An extract from the Elle magazine article reads, "Some years ago, a woman Gordon declines to name became a part of the Sonic Youth world, first as the girlfriend of an erstwhile band member and later as a partner on a literary project with Moore. Eventually, Gordon discovered a text message and confronted him about having an affair. They went to counselling, but he kept seeing the other woman."

Discussing the split, Gordon tells the publication, "It ended in a kind of normal way - midlife crisis, starstruck woman," and adds of their marriage counselling sessions, "We never got to the point where we could just get rid of her so I could decide what I wanted to do. Thurston was carrying on this whole double life with her. He was really like a lost soul."

Gordon admits the breakup came at a trying time for her as she had also been diagnosed with a non-invasive form of breast cancer called ductal carcinoma in situ (Dcis).

She explains, "I'm fine. It's literally the best (form of cancer) you can have. I didn't do radiation or anything, but I was like, 'Ok, what else is going to happen to me?'"

Gordon and Moore, who have a 19-year-old daughter, Coco, are still not officially divorced, but they are both dating other people.
