Heading into celeb hotspot the Chiltern Firehouse, Luisa gave us all a good look at her new rock... and her new purchases!
Looking lovely in a black collar dress and stylish mac, the former Apprentice star had a big smile on her face as she made her way into the London eatery.
Well, we would too if we had that gorgeous rock sitting pretty on our finger!
Adding to her arm candy, Luisa was holding onto multiple bags after shopping up a storm in the captial.
Christmas shopping already? Or just a festive treat for herself?
We're hoping the second after spotting that exciting bag from Louboutin!
Luisa's appearance in London comes after the star recently announced she is set to wed.
Last month, Luisa revealed she was engaged to her businessman boyfriend after he romantically proposed in Paris.
Whisking Luisa off to the French capital, her boyfriend popped the question over dinner with a view of the Eiffel Tower lit up in the background.
Announcing her news, Luisa shared a photo of her ring, along with the tweet: "Feeling like the luckiest girl in the world."
Following the proposal, Luisa threw an engagement bash to celebrate her happy news with pals.
Going all out for her special night, Luisa put on Brazilian-style performers, a jaw dropping ice sushi bar and a swimming pool!
Guests included her CBB housemates Casey Batchelor and Sam Faiers.
