Sinead O'Connor is ranting again, this time over the American Music Awards.

The Irish singer recently claimed on her blog that she had been asked to perform at the upcoming AMAs. Moreover, she said, producers wanted her to perform with a very special guest: Pope Francis.

In a blog post, titled " The AMA's and the Most Appropriately Named Company on Earth," O'Connor wrote, "6 weeks ago the appropriately named Dick (look closely at above photo) Clarke [sic] Productions contacted my record company saying they wanted me to perform at the AMA's. They would naturally need to run this by the network [on account of I'm the Pope's-photo-ripper] and would be back to us shortly-ish. Their hope was I would perform Nothing Compares, segueing into Take Me To Church."

The controversial singer, 47, said three weeks went by before her manager finally got an email from her record company, saying the AMAs passed.

But it was the reason why she said they passed that came as a big shock to O'Connor.

"It was decided that it would be 'A great hook'…to ask Pope Francis to appear with me," she wrote. "Since naturally their idea was not only disrespectful to the pope and to millions of catholics (The idea he ought consider lowering his feet into the disgusting world of show business and celebrity at all! Never mind with Sinead O'Connor) they didn't get a response and consequently I'm now not doing the show."

O'Connor railed, "I never heard anything so warped and disrespectful to both the Pope and myself, as well as millions of catholics…in my life."

She concluded with, "Very important to understand if you really give f*** about God, not just use he she or it it for a tv gimmick. God lives on earth and show business breaks his windows."

A spokeswoman for Dick Clark Productions declined to comment. The American Music Awards are scheduled to air Sunday, Nov. 23.
