On Monday (1 August), the reality beauty took to Instagram to share a throwback snap of her and her now one-year-old sister (n'aww!) but it wasn't the cute 'lil bubba that garnered the most attention...
In fact, it was Olivia's brown hair! Yep, you guessed it - she's also a fan of the bleach a la Holly Willoughby and Kim Kardashian.
"I love your brown hair!" wrote one of Olivia's Insta-followers, while another said, "Omg Olive! Brown hair really suits you! Think you should embrace it."
Olivia - loved up with island beau Alex Bowen - captioned her flashback photo, "First picture was a year ago today! My little munchkin sister turned 1 on Tuesday this week, she's getting more and more gorgeous as time goes on. My beautiful lil princess! Miss her loads," and it wasn't long before the likes came flooding in.
A right hair chameleon, isn't she? Move over, Kylie Jenner.
Last week, Olivia hinted that she might have plans follow in the footsteps of TOWIE's Chloe Sims and Jasmin Walia to launch her very own beauty channel.
She captioned a stunning selfie, "Since everyone keeps asking, as well as #OlivesOutfits [Olivia also shares the deets of her outfits every day, FYI!] I'm gunna to #BucksBeauty too!!" and lifted the lid on her favourite false lashes at the moment, Unicorn's Luna Fleur.
"You would do so well to launch a beauty channel, Liv! Tutorials and products you love!," wrote one fan underneath her gorgeous pic, while another said, "You should definitely do beauty vids."
The encouraging words come after Olivia told Reveal Online that she'd love to jump on the fashion design bandwagon a la co-stars Rachel Fenton - who has a clothing line with StyleGrab - and Malin Andersson who recently teamed up with online fashion go-to, Oh Weekend.
