Sharon Osbourne uncertain over reason for collapse

Sharon Osbourne has admitted that doctors have yet to identify the cause of her sudden collapse last month.

The 70-year-old was filming an episode of son Jack Osbourne’s series Night of Terror at a hotel in California when she passed out.

Osbourne was rushed to a nearby hospital but despite her taking numerous tests, doctors were unable to explain why she collapsed.

Returning to her show on TalkTV last night, she said: “I wish I could [explain] but I can’t. It was the weirdest thing – I was doing some filming and suddenly they tell me that I… [passed out], for 20 minutes.”

She added: “I was in hospital. I went to one hospital, they took me to another hospital and I did every test over two days and nobody knows why.”

Osbourne appears on The Talk, weeknights at 9pm on TalkTV.
