Sharon Osbourne has taken to her Twitter page to thank fans for their messages of concern following Kelly Osbourne’s recent seizure on the set of US TV show Fashion Police.

She wrote: "I want to thank everyone for their concern about @MissKellyO. She's doing fine she's at Cedars and is surrounded by the best doctors & love."

Kelly has also thanked fans for their “beautiful well wishes”, tweeting: "Thank U all 4 UR beautiful well wishes yes I did have a seizure they are just trying to figure out why? [sic]"

Fashion Police presenter Joan Rivers and her daughter Melissa were on set when Kelly collapsed on Thursday. Melissa told ET Online: "More than anything it was just scary. I just laid on the ground holding on to her until the paramedics came.

"She was disoriented and I just laid on the ground with her to keep her down because she kept trying to stand up.

"I made her look at me. I said, 'I'm here, stay with me, it's all fine'. I explained where we were."
