Luisa Zissman In Hospital After 'Burning The Candle At Too Many Ends'

Our favourite celebrities are dropping like flies this week - first Paul O'Grady was taken to hospital after a heart scare, then Rita Ora collapsed on a photoshoot, and now Luisa Zissman has ended up in hospital.

The former 'Apprentice' star has posted a picture of herself on Twitter, showing her lying in a hospital bed hooked up to an IV drip.

While she didn't reveal exactly what was wrong with her, she said it was the result of "burning candle at too many ends (sic)".

Despite her mystery illness, Luisa was still tweeting fans from her bed, insisting that she had "got no makeup on and straight hair".

She also wrote: "I'm not posing in my last pic I was dozing...."

Luisa has been busy of late, launching her Bakers Toolkit business, as well as attending a string of celebrity bashes, on top of looking after her three-year-old daughter Dixie.

Get well soon, Lu!
