Luisa, who came fourth in the last series of Celebrity Big Brother, will regularly appear on the panel of BB spin-off shows Bit On The Side and Big Brother's Bit On The Psych.
And if that wasn't enough, Luisa has also been announced as a 'roving reporter' for Bit On The Side too!
Speaking about her new Big Brother roles, Luisa revealed: "When I was in the house I didn't hold back…so I will be exactly the same on the panel.
"I'm really looking forward working with Emma [Willis], Rylan [Clark] and Iain [Lee] and can't wait to get to know this year's new batch of housemates."
Ben Frow, director of programmes at Channel 5, adds: "Luisa was a fantastic housemate in January and I'm delighted to welcome her to the team. I'm sure she'll have lots to say about this year's housemates."
Luisa first found fame on last year's series of The Apprentice. She was eventually crowned runner-up of the BBC1 show, after going head-to-head with Leah Totton.
The mum-of-one, who already owned a cupcake shop, went on to launch her own cookware brand Bakers Toolkit before signing up as a CBB housemate at the beginning of the year.
During her time in the house, Luisa formed a close bond with US star Jasmine Waltz and got up to some naughty mischief in the hottub with N-Dubz star Dappy!
Meanwhile, earlier this week Luisa confirmed that she is bringing out an autobiography called A Bad Girl's Guide To A Good Life. She will also release a baking book, Wicked Cupcakes, in July.
It's all go!
Big Brother is set to return to our screens next month and Emma Willis will continue to present the show, before joining Rylan Clark and Iain Lee for Big Brother's Bit On The Side.
