Oti Mabuse, 28, took part in the #10yearchallenge sweeping Instagram, by uploading a decade-old photo of herself on her account yesterday.
In the throwback snap, The Greatest Dancer judge sported a short black bob and wore burgundy lipstick.
The Strictly Come Dancing professional looked glum in the picture, as she did not smile for the photograph.
She appeared to have worn an off-shoulder garment as her chest was bare and she donned a long gold chain.
Alongside the image, she wrote: “Wow I’m sooo glad things have changed #10yearchallenge.”(sic).
She added: “Not sure why I look like an angry 18-year convict with hazel eyes but that was my end of the year ball pic (matric dance).
“You’d think I’d look a lot happier than that! Thank goodness for growth.”
Besides the decade old photo was a snap of the star at the launch of her new talent show, The Greatest Dancer.
For the special event, she wore her raven tresses in a high ponytail to show off her sparkling drop earrings.
Also, she covered her feet with a pair of thigh high boots and wore a one-shoulder shirt over a metallic miniskirt.
