Many of her 547k followers were quick to flood the comments section with their words of approval.
“Omg! Love this 🔥” wrote Lindy Klim.

“Loved mixing things up today @jade__kmakeup @dancastano @wearerushhunter @tina_n_hair,” she penned.
That’s not to say that she won’t be succumbing to the scissors - and bleach - in the future.

Her transformation comes just a few days after she shared that she would be keeping the Bartel surname, despite having no regrets over her split with her ex-husband and AFL great Jimmy Bartel.
Speaking to The Daily Telegraph, she reasoned that she “can’t imagine” having different surnames to the children she shares with her ex, Aston, four, and Henley, two.
“Right now, I want to have the same name as the boys,” she said when asked if she’d be reverting back to her maiden name of Coppolino.
“I can't imagine having another surname,” she added.
“If I didn't have children it would be a different story. I don't know what I might do in the future.”
The single mum has recently been linked to personal trainer Nathan Brodie, with the pair spotted on a romantic date at a park in Melbourne last month.
