Married At First Sight Australia Star Heidi Latcham Sports New Straight Hair-Do In Transformation

In her most recent Insta, Heidi - who split with Mike Gunner after leaving the series - can be seen posing in a tiny leopard print bikini with her new, straight hair swept into a big blonde bun on top of her head.

She can be seen rocking the straight bun up-do again further down on her grid, as she cheekily munches on a chip alongside her pal.

Another snap, where Heidi's curls had returned, show the reality star's locks are a significantly lighter shade of blonde, while she's sporting a tamed back makeup look, and lighter eyebrows, too.

"OHHHH that blonde is your shade for SURE," one fan wrote in the comments.

*Spoiler alert*

Mike and Heidi sadly announced their split at the Married at First Sight Australia reunion special, which is yet to be shown in the UK.

In the special, Mike explained: "Right after the final vows, Heidi and I went back to the Gold Coast together but it didn't take long and the wheels started coming off."

"It was great for like two days and then it just went to s***. And then I haven't spoken to him since," Heidi added.

Now Mike works as a hairline tattooist and, though he went on to date model Jessica Williamson after Heidi, he is currently single.

Speaking during the series' second Grand Reunion, which also featured cast-members from season five of the show, Mike added that he still held love for Heidi, and wanted to make things work.

"She could light up a room like no one I've ever met. Everybody fell for it, and I see it as a huge missed opportunity," he confessed to the experts.

"I don't know if I've made peace with it, even two years later. I made a lot of mistakes. They were hurtful to her and damaging to our relationship".

Is it bad we're still kind of rooting for these two?! Just get back together already guys!
