She might now be a TV star with glossy hair and a fancy manicure, but beneath the makeup she's just the same old Stacey.
And Stacey Solomon showed just how true that is on Thursday, as she shared an old school photo with fans.
While she was makeup-free and clearly young in the shot, with her wide beaming grin and pretty face, it was instantly clear just who was pictured.
"i'm cracking up so much! Everyone else's are so cool," wrote Stacey.
"Here's my first day at secondary school."
The picture showed the now mum-of-three in her school uniform, hair tied back in a neat ponytail.
Looking sweet and smart, she smiles for the camera.
Stacey was just 17 when she had her first child Zachary, the oldest of her three sons.
The 31-year-old's life was transformed at 20 when she came third on The X Factor.
Hugely popular with viewers, she went on to appear on the tenth season of I'm A Celebrity, where she was crowned the winner.
Now a Loose Women panelist, Stacey posts daily scenes of family life to her Instagram account, where she has nearly four million followers.
