Rock legend Stevie Nicks had her long-time friend Mariah Carey's back in a beef with fellow American Idol judge Nicki Minaj. "How dare this little girl!" Nicks said in an interview. "If I had been Mariah, I would have walked over to Nicki and strangled her to death right there. I would have killed her in front of all those people and had to go to jail for it." Nicks apologized soon afterward and Minaj never commented at all.
