Zoe Foster Blake has a twin and you've definitely met him before.

Yesterday, Zoe Foster Blake shared some throwback photos on Instagram.

Her mum was visiting and she had brought all of Zoe’s old school photos with her.

Like everyone’s pics from the 80s’ and 90s’ they reminded us of a time long ago – when hair was bigger and eyebrows were thinner – and, erm, crystal fish necklaces were in fashion.

Those were the days. Image via Instagram.

Also, Foster Blake has a twin and you've definitely met him before.

Thrown into the mix was this photo of a young Zoe and you can definitely spot the resemblance. Yep, Sonny made a little cameo in Zoe's walk down memory lane.

Put some pig-tails on him and they're twins.

Not that it should be entirely surprising when children look like their biological parents because, well, DNA.

Here are some more examples....

Happy 4th y'all! #GoldenHour @avaphillippe ❤️❤️????????
