Known for having blonde hair during her two reality TV stints, Alex shared a photo on Instagram this week rocking a fiery shade of red.
“Guess who’s back,” she captioned the post alongside an orange heart.
The 29-year-old previously dyed her hair a similar colour in 2019, before returning to her signature look shortly after.
Fans were quick to compliment Alex’s new ‘do in the comments.
“You absolute beauty,” one person posted. “Inside and out.”
“Welcome to the red side,” someone else added, while others wrote “stunning”, “gorgeous” and “beautiful”.
Alex recently entered the third trimester of her pregnancy, and regularly posts content online updating her followers.
The former reality star announced her pregnancy back in January after going Instagram official with her partner Carson Jory the previous November.
“I wonder if you’ll have your father’s eyes? Will be you be stubborn like your mother?” she captioned the announcement.
“See you soon little darling.”
Australia was first introduced to Alex when she appeared on the fourth season of The Bachelor in 2016 with Richie Strahan.
She ended up winning Richie’s heart and the pair left the show together, only to separate the following year.
The couple crossed paths again in 2019 when they were both contestants on the second season of Bachelor In Paradise.
During that time, Alex found herself caught in a love triangle with Bill Goldsmith and Brooke Blurton, who is set to star on The Bachelorette this year.
Bachelor star Keira Maguire’s new look
Fellow Bachelor alum Keira Maguire, who appeared alongside Alex on Richie’s season of the dating show, also recently debuted a transformation on Instagram.
Keira was notable for being the ‘villain’ in her original season, before having two appearances on Bachelor In Paradise in 2018 and 2020.
The reality TV queen shared a video on her Instagram story earlier this month looking barely recognisable.
The 35-year-old’s face appeared much more plumper than normal after spraying a hydrating mist.
“It’s so hydrating, it literally makes my face blow up like a blowfish,” Keira told her fans.
“You can actually put this on over make-up,” she added. “I’ll sometimes just spray it for hydration!”
Keira previously admitted to having a $35,000 ‘makeover’, which included a nose job, breast augmentation, lip fillers, botox, laser skin treatments, vampire facials and eyebrow tattoos.
