To be fair Sinead totally started it.

So, now it seems that Miley Cyrus and Sinead O'Connor are in a raging feud. It's pretty amazing who will just jump down your throat when you've gained a TON of spotlight.

Things started when Sinead released an open letter to Miley telling her that she's being "prostituted" by the music industry. Miley responded with a resounding 'NOOOOOOO!' and O'Connor wrote her another letter.

Yikes.

Miley tweeted out to Sinead that if she wanted to meet up to give her the details in her next letter. In addition Miley retweeted some of Sinead's tweets from a few years ago about needed to get back on medications and reaching out for a psychiatrist.

We don't foresee this ending anytime soon.
