Kelly Osbourne cracked her head open ballroom dancing.

The former 'Dancing With The Stars' contestant was hospitalised over the weekend with the injury and now her mother Sharon has revealed she hurt herself after a dance move she was showing a male pal went wrong.

Sharon revealed on her TV show 'The Talk': "They all went to a club to see this DJ. And so anyway, she was dancing with somebody that said, 'Teach me how to ballroom dance.' So she did, and the guy takes her down to a dip and as he dips her down, she hits her head on the amplifier. So it split her head open.

"Anyway they cleaned it up. She thought she was fine, she went back to her hotel room and fainted twice. And then they called the ambulance and she fainted in the ambulance.

"She went to the Mercy Hospital. And she had stitches in her head and she has a severe concussion so she was awake for two days."

The showbiz matriarch insists her daughter is now "fine" and recuperating at home.

She added: "She's fine, she's just got a very sore head. I flew her back home. And she's in my bed with her doggie. I stayed in the hospital with her for two nights. But thank god she's fine and we're all happy."

Kelly originally broke the news of her injury on her twitter page.

She wrote: "I just want 2 thank all the incredible doctors and nurses @ Mercy hospital in Miami 4 taking such good care of me u guys really are amazing!

"Long story short I cracked my head open then kept passing out I have the all clear my mum came 2 get me. (sic)"
