Miley Cyrus has opened up about her feud with the late Sinead O’Connor after the Irish singer claimed the pop star was being “pimped” out.

Following O’Connor’s death in July aged 56, many fans remembered the open letter penned by O’Connor to Cyrus.

The letter addressed the then-recent release of the music video for Cyrus’s “Wrecking Ball”, in which she is seen swinging on a demolition ball while nude.

After Cyrus said that she’d been inspired by O’Connor’s accompanying visuals for her 1990 hit “Nothing Compares 2 U”, O’Connor replied to the then-20-year-old “in the spirit of motherliness and with love”.

She told Cyrus that it wasn’t “‘cool’ to be naked and licking sledgehammers in your videos”, adding that she is being “pimped” by the music industry.

Cyrus has now addressed the letter, as well as her reaction at the time, in new ABC documentary Endless Summer Vacation: Continued (Backyard Sessions).

“At the time when I made ‘Wrecking Ball’, I was expecting for there to be controversy and backlash, but I don’t think I expected other women to put me down or turn on me, especially women that had been in my position before,” the 30-year-old recalled.

“So this is when I had received an open letter from Sinéad O’Connor, and I had no idea about the fragile mental state that she was in.”

At the time, Cyrus responded by making fun of old tweets sent by O’Connor during a period of ill mental health. She compared the singer to former Nickelodeon child star Amanda Bynes, who was also struggling mentally.
