Kelly Osbourne regrets nearly attacking a fan who recognised her while she was shopping for clothes.

The singer, who reached fame after starring on the show based around her hectic family life - The Osbournes - nearly seriously hurt a fan when she was recognised in London fashion store Topshop.

Osbourne said: 'This girl came up to me and shouted, 'That's Kelly Osbourne!' and pointed her finger in my face - literally her fake nail touched my nose and I just flipped.

"I grabbed her hand and said, 'Don't f**k with me, or I'm going to break your f**king finger off.'"

But Osbourne insisted she would react differently now she has been through rehab and therapy. She said: "I'd probably say, 'Can you possibly not put your finger so close to my face, but it's nice to meet you.'

"I'm so over fighting or being upset when people say something horrible about me."
