She is one of the most recognizable reality TV stars.

But Martha Kalifatidis looked very different on Tuesday when she unveiled a brand new look on Instagram.

The Married At First Sight star, 35, ditched her raven locks in favor of warmer red strands with highlights.

In a photo shared on Instagram, Martha showed off her new locks as she posed with her fiancé Michael Brunelli.

“Today was a good hair day,” she captioned the photo.

It comes after Martha revealed she was at the “low point of her life” when she was pregnant with her first child, Lucius.

The Married At First Sight star and her fiancé welcomed their son in February this year.

Speaking the KICBUMP podcastMartha opened up about the dark side of her pregnancy, describing her tough battle with the debilitating pregnancy disease hyperemesis gravidarum (HG).

“HG, there’s no laughing matter. When you’re in the middle of it, you’re so sick you’d do anything to escape it. It’s so hard to relive those moments,” Martha said.

“I remember being so sick and thinking, ‘I’ll never forget this, this is the lowest point of my life.'”

Although Martha has never suffered from depression before, she said the emotional toll of the pregnancy was huge.

“This pregnancy was the lowest, it was dark, it was depressing,” she revealed.

“It won’t stop until you have the baby. Mentally and physically it hits you on both sides,” she added.

It comes after Martha admitted she feared she was “starving” her newborn son Lucius after the baby refused to eat for weeks.

“Lucius was born with jaundice, so he didn’t eat for the first four weeks of his life,” she said Nine honey earlier this month.

“He’s lost a lot of weight. That was the most stressful thing for me to worry about and obsess over.”

Martha continued, “He didn’t gain weight and didn’t gain his birth weight for nearly four weeks.

“As a mom, you’re like, ‘Oh my God, is this baby starving? What am I doing.”

Fortunately, Lucius, now three months old, started to eat well and has now reached his target weight.
