Amber shared the 'now and then' photograph with fans on Instagram today (21 October) to celebrate her milestone year.
In the childhood snap, five-year-old Amber has short brunette hair brushed into a side parting and is sporting a sweet pair of pink plastic glasses.
Alongside it, the model and mum-of-one has posted a picture of herself now aged 30.
Uploading it to the photo sharing site, Amber commented: "5 years old...... 25 years later." Aww!
Earlier this month, Amber showed off an edgy new hairstyle while playing with her baby son Sebastian 'Bash' in a swimming pool.
She may not have had a buzz cut aged five, but other than that, we don't think she's changed much at all!
