Lord Sugar may be shocked to hear his hopeful used to be a regular guest at orgies, according to The Sun.
The newspaper claims the 25-year-old took part in sex parties run by a company called Killing Kittens.
A 'friend' of the retail entrepreneur from St Albans claimed: “Luisa is sex mad. She is an exhibitionist and loves being centre of attention.
“These crazy sex parties were perfect for her and she loved them. It’s fair to say she didn’t hold back. Some of the stuff that went on was not for the faint-hearted.”
The revelation comes after photos of the mother-of-one emerged online, showing her topless, posing in lingerie and getting up to all kinds of mischief with female pals.
In her show profile, Zissman describes herself as confident, logical and outspoken, and cites her greatest business achievement to be the ability to create new jobs through the success of her businesses.
She lists her favourite business brands as Christian Louboutin and Virgin Atlantic for their strong brand identities. Her first job was as a Saturday girl in an estate agent and she now owns her own cupcake shop, baking website and electronics business.
She also said: “I have the energy of a Duracell bunny, sex appeal of Jessica Rabbit, and a brain like Einstein.”
'The Apprentice' returned to BBC One for its ninth series this month and for the first time ever, 'The Apprentice' candidates had to reveal their business idea right at the start of the show.
Each candidate is required to demonstrate business sense, creativity and leadership in order to impress Lord Sugar, Nick Hewer and Karren Brady, but only one applicant will triumph and become Lord Sugar’s next business partner and win his £250,000 investment.
