Luisa, who was runner-up on this year's series of The Apprentice, donned her best denim skinnies before attending a Jeans For Genes Day charity bash.
The mum-of-one, 25, teamed her jeans with a pair of patent peep-toe heels and glammed up her look with a dressy pink and black patterned top.
After attending the event, which was held at London's Jewel Bar, Luisa headed out for a night on the tiles with her friend, Capital FM DJ Greg Burns.
The pair spent the rest of the night at the exclusive Groucho Club before leaving together hand-in-hand. Judging by the smile on her face, Luisa had a great time with her new pal!
Sharing a photograph of herself pretending to kiss Greg with her fans on Twitter, Luisa jested that Radio 1 DJ Greg James was no longer her favourite Greg.
She commented: "Move over @GregJames, in Groucho with @GregCapital who is my new fav Greg on radio!!"
Despite her night of partying, Luisa was up bright and early this morning. She has since tweeted: "Yawn, great night out but back to work!"
