After spending the last six weeks filming in Greece for Geordie Shore, Holly celebrated wrapping up the show's eleventh series (oh, and her recent birthday!) by heading to the salon.
Treating her bonce to a little TLC, the 23-year-old opted to go blonder than she has done so before, and we have to say, we're absolutely loving her revamped tresses.
Fancying a change from her usual caramel-hue, Holly opted to lighten her locks all over and is now rocking one seriously gorgeous honey blonde head of hair.
She's not the only famous face to go blonder than blonde in the last few months as Katie Price and Khloe Kardashian have both reached for the lighter dye too.
Even pregnant Big Brother star Imogen Thomas decided it was time to wave goodbye to her chocolate locks, colouring her bonce an envy-inducing golden shade.
After sprucing up her tresses, Holly finally got to show off her new look as she headed to In The Style's summer party in London yesterday evening.
Showing her support for co-star Charlotte's 'Nostalgia' line with the online retailer, she joined her bestie at the star-studded bash in Covent Garden.
While Charlotte looked gorgeous in a stylish red playsuit, Holly put her fabulous figure on display in a fail-safe little black dress.
The girls enjoyed a few drinks with their fellow female castmates Chloe Ferry and Marnie Simpson (who couldn't have looked more loved-up with rumoured fiance Ricky Rayment).
Inside the party, they joined a handful of TOWIE stars including Lauren Pope and Jasmin Walia.
