Kelly Osbourne Puts 'F-cking Tw-t' Prince Harry on Blast for 'Whining,' Opens Up About Her Father Ozzy's Addiction, Rehab & Being Terrified of Relapsing

On relapsing:

“I’m scared of relapse. Terrified of it. Absolutely terrified. And it’s not necessarily the drinking that I’m afraid of. I know I don’t care about that. It’s more the drugs. I know it’s my parents’ theory it’s the drinking for me, because they know I have one drink and it’s done.”
