The former Apprentice candidate looked the picture of happiness as she posed on the red carpet last night, gorgeous diamond clearly on show!
Well, we don't blame her!
Mum-of-one Luisa partied without her fiancé last night, looking lovely in a black dress from MiAmor Bridal & Prom Boutique.
The businesswoman surprised fans in October by announcing she'd become engaged to her mystery beau in Paris, showing off the beautiful ring he'd presented her with during a romantic evening.
An expert told Reveal the flashy rock could be worth a cool £1.5 million!
Luisa has said previously that her man prefers to remain out of the spotlight, so that's why he hasn't been accompanying her on red carpets or popping up all over her Twitter feed.
This will be the star's second marriage. Previously, she was wed to businessman Oliver Zissman, the father of her daughter Dixie.
Yesterday, she left him at home as she presented an award alongside Russell Kane at the Paul Raymond Adult Industry Awards at Spearmint Rhino nightclub.
