'Fashion Police' host Kelly Osbourne thought her mother, Sharon, was going to die when she was struck down with colon cancer in 2002.
The 28-year-old star said the devastating news made her realise the importance of life and forced her to appreciate her mother more, reported Contactmusic.
"I became my mum's nurse 24/7. I gave her injections and medicines when she had seizures. I even had a parking space at the hospital with my name on it. I thought I was going to lose her - it was awful.
"I used to wake up every morning and go, 'My mum is so stupid, she doesn't know anything'. Now I wake up and I go, 'Mum is so smart. Why didn't I listen to her when I was younger? She's the best mother - and friend - in the world and it makes me want to cry saying that," she said.
