London, April 29 : Former Atomic Kitten Kerry Katona thought she was an alien during her five-year struggle with bipolar disorder.
The singer, who was at the Oxford Union with hubby Mark Croft to deliver a talk, revealed the effects the manic depression had on her.
"I sat on the bed and said, `Mark, I'm an alien' - and I really thought I was an alien," the Sun quoted her as saying.
"I didn't brush my teeth for a week. It's part of my personality," she added.
