The former Strictly Come Dancing runner-up, who appeared on the BBC Ballroom dance show with Kevin Clifton in 2016, whipped her 131,000 Twitter and 494,000 Instagram fans into a frenzy with the adorable upload of her beaming a cute smile for the camera as she cuddled with her mum.
Louise, now 43, was captured with shoulder-length brunette hair which she wore in a side parting, a world away from her current golden tresses.
Her younger self wore a pink dress adorned in flowers as she cosied up with her mother, who sported a V-neck cream blouse.
Louise posted the snap along with a loving message to her mum.
She wrote: “Mum I loved being with you yesterday I’m so lucky to have you, not only my mum but my best friend too.”
Many of her followers left a comment on the star’s throwback.
One Twitter user wrote: “Lovely photo Louise,” while one of her Instagram followers added: “Two peas in a pod….beautiful.”
“You look so like her now,” a third quipped.
Reports recently emerged claiming that Louise Redknapp had hired a clairvoyant to help her through her break-up with Jamie Redknapp, 44.
The former Eternal singer was granted a divorce from her husband of 19-years in December after she previously referred to herself as a “Stepford Wife”.
According to reports, the mother-of-two has been pursuing inner happiness through sessions with crystal healer Emma Lucy Knowles, who charges £220 per visit.
A source told The Sun: “Louise was going through a tough time following her divorce.
“But rather than going to see a therapist about her problems, she decided to see Emma Lucy and has really been pleased with the results.”
The insider continued: “It helped her clear her mind and put the stresses from her divorce behind her.
“The sessions aren’t cheap and Emma recommends a minimum of four to get the best results, but it’s a price Louise was willing to pay to find her happiness within.”
Earlier this month, Louise Redknapp reflected on her time as a single mum during a car trip with Tess Daly.
In a series called Heart’s Confessions Of A Celebrity School Run, with VW Tiguan Allspace, Louise was questioned by Tess about the school run with her and Jamie’s sons Charley, 13, and Beau, nine.
Comparing her two boys to each other, she spilled: “I drop the older one at the bus stop in the morning.
“The older one is quite stroppy, so he always gets out of the car on an argument.
“The little one is just beaming all the time,” she continued. “He runs, gets in the car, he’s happy and telling me about his day.
“And the older one, this is how they change, he’ll get in the car and say ‘What’s for dinner?'”
“I say, ‘The good news is, you can have whatever you want. The bad news is you’ll have to wait ‘cos I haven’t been to the supermarket yet.'”
