Brittney sported long dark brunette hair on the show, which aired just weeks ago.
But the Channel 10 reality program wrapped filming almost 10 months ago back in December, giving Brittney plenty of time to switch up her look since then.
Brittney’s 98,000 Instagram followers were quick to praise her new hair transformation, with her selfie attracting dozens of supportive comments.
“Blonde hair is the way to go 🙌🏻🙌🏻 Looking phenomenal,” one fan commented.
Another wrote, “That hair colour looks sooo good on you! You look gorgeous.”
One fan even said compared Brittney’s new vibe to actress Kate Hudson!
“I was scrolling and thought ‘Geez kate hudson looks amazing today’ and then realised oh my lord its you. Looking amazing!”
Brittney first shot onto our screens as an intruder on Nick "Honey Badger" Cummins' season of The Bachelor in 2018. She later starred on Bachelor in Paradise in 2019 and 2020.
While she left Paradise with co-star Jackson Garlick this season, with the couple having every intention to pursue a relationship in the real world outside of the show, the pair split up shortly after leaving Fiji.
"I'm here for my final update: @jacksongarlick and I aren't together, but he is an amazing guy," she wrote on Instagram last month.
'We did catch up on the outside, I did meet his friends & family, and we had good times. Unfortunately, life gets in the way, and we are now just friends."
