The cupcake business owner, 26, came second on the BBC1 series and has since launched her own brand, Bakers Toolkit.
During her time on the show, Luisa described herself as "having the energy of a Duracell bunny, sex appeal of Jessica Rabbit and a brain like Einstein".
Luisa has a young daughter called Dixie with her estranged husband Oliver and is a regular on the London party circuit.
Speaking to Reveal in November, Luisa stressed that, despite her celebrity image, business is however her main focus.
She said: "First and foremost, I'm an entrepreneur and businesswoman. Everyday I'm in the office. I have an amazing team of people around me and couldn't do everything alone but I work pretty hard."
