Apprentice runner-up and St Albans' Dixie's Cupcakery owner, Luisa Zissman, enters Celebrity Big Brother house

The owner of Dixie’s Cupcakery in St Albans joined celebrities including reality TV star Sam Faiers, US model Jasmine Waltz and N-Dubz rapper Dappy on the Channel 5 reality TV show, which aired at 9pm.

Luisa, who took second place in last year’s BBC One show, The Apprentice, said in a video clip aired before she entered the house: "You either love me or you hate me, but just ignore all those haters.

"I have the energy of a Duracell bunny, the sex appeal of Jessica Rabbit and a brain like Albert Einstein."

The mother-of-one said: "I wouldn't say I was promiscuous, but I'm very open to exploring my sexuality", adding: "I just want to have fun."

The cupcake business owner, who wore a red skater-dress, walked out to cheers from the crowd.

When asked how she will act in the house, Luisa said: "I'm always the life and soul I think, but there's probably loads of other crazy people in there."

She added: "I hope there are loads of bonkers people in there."

Before entering the house, each celebrity was handcuffed to another contestant.

Luisa was paired with American boxer, Evander Holyfield, who famously had part of his ear bitten off by Mike Tyson.

Twelve celebrities entered the house tonight.

Among the contestants were presenter, Jim Davidson, Daily Mail columnist, Liz Jones, and Made In Chelsea's Ollie Locke.
