Wearing a pink crop top and matching pink bucket hat, Coco had short blonde hair, the total opposite to the long brown locks she normally rocks.
"Turns out I’m not ugly, just needed to borrow Serena’s hair," she wrote, referencing a mannequin she nicknamed Serena earlier this year for a first aid course. Serena had blonde hair, which Coco has seemingly taken for the snap.
"You suit blonde soo much!" one follower wrote, while another former MAFS star Hayley Vernon added, "You look THAT good blonde."
"I LOVE this!" another user said.
"Wait is that real or a wig?? Looks absolutely stunning," a third asked.
"Hahaha definitely a wig," Coco responded, calling it "a lockdown essential".
"You NEED to be a blonde!" someone else added.
Others wrote that she was a "stunner" and a "bombshell", while some simply commented with the fire and heart eyes emojis.
Coco is no stranger to a makeover and earlier this year, choosing to dye her hair red.
At the time, she told her followers there was a reason behind the transformation.
"There is a method in my madness." Coco said. "I wanna go out with only people who follow me on Instagram being like 'oh my god, is it you?' This way, no one will know."
She went on to say: "So yeah, I don't know, variety is the spice of life, isn't it? I've been brown, I've been blonde, and I just wanted to try something else. And I don't really care if you say you liked it better before."
After appearing on the reality show earlier this year and not finding love with her TV husband Sam Carraro, Coco seems to have found love with a mystery man, who she has yet to share a snap of on social media.
Coco has casually mentioned she has a partner who she is seemingly living with during lockdown.
On her Instagram Stories on Monday, Coco joked that her favourite work out other than a classic gym session is "running through my house naked after a shower like a three-year-old yelling, 'Rudy nudie!' while my partner is on a Zoom work meeting".
