"I wish I could but I can't [tell you why]," Sharon said during Tuesday's episode of U.K.'s "The Talk." "It was the weirdest thing – I was doing some filming and suddenly they tell me that I [passed out] for 20 minutes. 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."
