After she converted to Islam, she said she wouldn't be around "disgusting white people"
She became an unofficial Catholic priest (weird considering she publicly called 'em out for being pedophiles)
She boycotted the Grammys
The whole SNL thing
She wouldn't play the American national anthem before her shows (which I get, she's fucking Irish)
I don't know much about her, and didn't spend much (actually any) time researching this. It's the first article I found on my first google
