She shot to fame as the bubbly brunette runner-up on The Apprentice, and despite narrowly missing out on the crown, Luisa Zissman has proved that she is no second fiddle. The 25-year-old entrepreneur has been showing off her figure in a series of tiny bikinis and figure-hugging dresses during her holiday in Marbella.

And now Femail can reveal the secret behind her killer curves. Luisa paid for a fat-freezing treatment called Lipoglaze at LoveLite clinic in Harley Street last week to get in shape for her Spanish trip. The BBC1 reality show star is reportedly extremely self-conscious about her womanly hips and was desperate to lose a few inches off them before she hit the beach. At the time she tweeted: 'Having lipoglaze with loveliteuk in Harley Street! Marbella here I come! X
She later added: '@NataliePanayi ‪@LoveLiteUk it was fabulous I can recommend xx'
The treatment works by first gently heating and then rapidly cooling the target area. This causes the fat cells to crystallise and permanently destroys up to a third of fatty deposits per session. The body then naturally eliminates this waste tissue over the next few weeks.
