Coleen, 27, posted the picture on Facebook this afternoon (13 March) for 'Throwback Thursday' and she is rocking a rather fetching bob/ bunches hair 'do.
The star is dressed ready for school and is posing with her arm around cheeky-looking Joe at the family home.
Sharing it on the social networking site, Coleen said: "Throwback Thursday - With my brother Joe in my school uniform x."
More than 2,000 people have 'liked' Coleen's post and many fans have commented on how sweet they look.
One of the star's followers said: "Lovely photo of you both x." Another added: "Coleen, you haven't changed!! Lovely photo."
Coleen is now a mum to her own cute children, sons Kai and Klay, and back then wouldn't have had a clue about the path her life would take.
Once thing's for sure though, with that hairstyle she was always destined to be a style icon!
