Rock matriarch Sharon Osbourne was left bedridden over the weekend (22-23Nov14) after she was struck down by a nasty bout of vertigo.

Ozzy Osbourne's wife reveals she was en route to a star-studded event at author Jackie Collins' Los Angeles home on Saturday (22Nov14) when she suddenly fell ill and threw up in her car.

The dizzy spell prompted Osbourne to head home and she spent the rest of the weekend recovering in bed.

Returning to work as a co-host on her U.S. daytime show The Talk on Monday (24Nov14), she explained, "I did a charity event on Saturday. Afterwards, I was meant to go and do something with Jackie Collins and Kathy Griffin and Raquel Welch. I'm in the car going from the event to Jackie's and suddenly (I vomitted).

"I suffer from vertigo and literally, I was, like, two days I... couldn't look up, (or) down... I was totally (incapacitated)."
