Miley's Wrecking Ball video was inspired by Sinead

Miley Cyrus has angrily hit back at Sinead O’Connor following the Irish singer’s open letter to the former Disney star.

Sinead, 46, penned the note on her website after Miley admitted that parts of her controversial Wrecking Ball video were inspired by Sinead‘s famous crying scenes in 1990’s Nothing Compares 2 U.

In the message Sinead tells Miley, 20, not to let herself be prostituted’ and warns against the dangers of being exploited.

I am extremely concerned for you that those around you have led you to believe, or encouraged you in your own belief, that it is in any way “cool” to be naked and licking sledgehammers in your videos,’ she writes.

It is in fact the case that you will obscure your talent by allowing yourself to be pimped, whether it’s the music business or yourself doing the pimping.

You are worth more than your body or your sexual appeal. You have enough talent that you don’t need to let the music business make a prostitute of you.

The message you keep sending is that it’s somehow cool to be prostituted.. it’s so not cool Miley.. it’s dangerous.’

But Sinead‘s concerns haven’t gone down well with Miley, who’s fired back at the songstress on Twitter.

Sinead. I don’t have time to write you an open letter cause Im hosting & performing on SNL this week,’ the We Can’t Stop singer Tweeted.

So if youd like to meet up and talk lemme know in your next letter. :)’

Miley‘s also courted controversy by comparing Sinead to troubled actress Amanda Bynes, who has had a very public battle with mental health problems.

Before Amanda Bynes…. There was….,’ Miley Tweeted with a screen grab of a Twitter rant posted by Sinead earlier this year, where she says she needs the urgent help of a psychiatrist.

But Miley‘s been slammed for making a jibe about mental illness, with one fan responding: How awful of you to make fun of Mental Illness! Not Cool!’

Another adds: wow I thought you were OK before but you’re a really nasty little person!’
