Sinead O’Connor has said she has no interest in meeting Miley Cyrus after the pair became embroiled in a bitter online feud.

Tonight, Cyrus tweeted a line from O'Connor's famous song Nothing Compares 2 U to further fuel the feud.

"I went to the doctor guess what he told me, guess what he told me. He said girl you better try to have fun. No matter what you do," a message to her followers read," she tweeted to her followers.

Speaking to the Sunday Independent’s Barry Egan earlier today, Sinead O'Connor said she was “glad” with what she had said to the Wrecking Ball star in three open letters.

Cyrus’ offer for a meeting came after the Irish singer revealed she was "extremely concerned" about her Wrecking Ball music video and warned her not to be exploited by the music business, in an open letter on her website.

The 20-year-old mocked the Nothing Compares 2 U singer in a series of Twitter posts, likening her to troubled actress Amanda Bynes, who is undergoing psychiatric treatment and tonight she tweeted a line from the song.

She also hinted at Sinead's former health problems and posted a picture of her tearing up a photo of the Pope, as well as a screenshot of her older tweets from 2012, when she asked Twitter followers to recommend a psychiatrist.

“I know what it's like to be a 20-year-old woman and everybody is on your case and wants to go on telly giving out about this, that and the other and I don't want to get into that,” O’Connor said.

“I'm happy that I've written the letters directly to her, that I've written on my site, and I'm not interested in engaging with her on another level.

“I'm certainly not interested in putting up on someone who is 20 years of age which doesn't mean I'm not glad I said what I had to say in the last few days.

“She's entitled to feel how she feels and I'm entitled to feel how I feel.

“I'm not going to get into slagging her off.

“If I had to say anything to her I think I would ask her nicely if she would apologise to Amanda Bynes because I think Amanda Bynes being dragged into the issue when she's an innocent party and had nothing to do with it and at a time where she is extremely vulnerable. She's in treatment for a mental health condition.

“What Miley did yesterday in berating her for that, in the same sentence as myself, has exposed poor Amanda to a certain amount of negative press from some of the top American media today."

O'Connor later added on the Late Late Show: "I don’t pitch myself as a role model.

"I was upset on behalf of Amanda Bynes. I thought it was a nasty thing to do. It was a nasty time to expose a girl.

"I doubt Miley is the type of person who sat down and said that I want to hurt Amanda Bynes.

"Music is being murdered, The power of rock and roll to move things has been murdered.

"I was asked to wear mini-skirts and grow my hair and that is why I shaved my hair.

"The music industry has far too much creative control."
