The former Bachelorette also shared a video of her new locks, writing: "Before v After Extensions, and for those asking... @ryan.tnb used 50 pieces of keratin bond extensions on me."
Friends and fans were quick to share their love for the new look, with even fellow Bachie star Alisha Aitken Radburn writing: "So gorge."
"Lovely @happylittlebeckymite you also rock the short style too," one user wrote.
Another added: "Perfect colour match! Wow! "
Becky's new do comes after she went official with her new man, James Bevitron - a fellow Newcastle local.
She announced her new romance in an adorable selfie, where she and James glowed with happiness as they smiled for the camera.
“Yesterday I took this pic and thought it was hella cute...This is what a happy Becky looks like and it feels pretty damn good,” she captioned the post.
“I feel understood, appreciated and loved by you and that’s a pretty amazing place to be...Here’s to many more kombi #vanlife adventures with you.”
While Becky didn't find love on the Bachelorette, after her ex Pete Mann infamously broke things off with her via FaceTime after three days, she looks to be happier than ever.
And it's not just Becky who's putting her unsuccessful Bachelorette stint behind her, with Pete also moving on with a former flame, Rachel Evans.
