rage. Demonic eyes. I wanted to kill everybody," she told London's Mirror
"I remember the first time my husband Carey p––d me off during my pregnancy and I bit his head off ... his eyes glazed over, he was so scared," says Pink. "He realized this is how it was and he better not say another word. I wasn't pukey – I was just angry."
