The Newcastle beauty joined a slew of famous faces at a party hosted by Jeans For Genes in the capital, and making sure she was dressed to impress for the occasion, Holly certainly turned heads in her glamorous getup.
Of course, the starlet made sure to don her denim for the bash, ditching your usual shade of jean for a black high-waisted pair that featured cool rips by the knee.
Turning her casual ensemble into an outfit that oozed sex appeal, Holly then teamed her jeans with a fitted white shirt, leaving it open to flash a hint of cleavage and her black bra underneath. She then finished off her look with stylish gold jewellery, matching her clutch bag to her peep-toe heels.
On the beauty front, Holly looked nothing short of gorgeous, wearing her luscious locks in cascading curls and sporting bold brows, shimmery eyeshadow and plenty of lipgloss for her make-up.
Inside the event, the 23-year-old rubbed shoulders with her fellow reality stars including TOWIE's Mario Falcone (who appears to be back together with girlfriend Emma McVey), pregnant Imogen Thomas, Ibiza Weekender's Imogen Townley and her BFF Charlotte Crosby who was caught kissing Love Island's Max Morley!
Not stopping her evening there, Holly then went on to party at London nightspot DSTRKT with Charlotte, Max and Geordie Shore's Kyle Christie.
Holly has been dating her co-star Kyle since last year. While the pair are currently together, Holly did recently admit viewers will soon watch her and Kyle split up.
Speaking exclusively to Reveal, the starlet revealed her and Kyle's relationship was put to the test while the pair were filming for Geordie Shore's new series in Zante.
"Me and Kyle went through a lot of sh*t in this series that's about to come on soon that basically meant we broke up," she told us. "Soon people are going to watch me get my heart completely broken."
While Holly made sure not to reveal exactly what went on with herself and her beau, she did reassure us the pair are now back on track. Holly added: "At the minute we are really, really happy, but we're taking things really slow."
That hasn't stopped Holly from considering quitting Geordie Shore, though, in order to save her romance.
Holly recently admitted: "Being with Kyle, he's more important to me than the show is... If it came to that point where I had to choose him or the show, I would choose him every time."
