The 21-year-old, daughter of rocker Ozzy Osbourne and his music manager wife Sharon, credits living on her own in her luxury £1 million apartment - a birthday present from her parents - for her new slimmer figure.
She says, "I live on my own now, so I don't cook.
"If hungry I eat chocolate. That's my only diet - and I've lost a bit of weight."
