Actress Amanda Seyfried proved even celebrities really do grow up when she posted a flashback picture on Instagram in celebration of boyfriend Justin Long's birthday.
The 28-year-old showed exactly what a difference the years and a good orthodontist make, much to the delight of her fans (not to mention Team MyDaily).
Turns out us mere mortals weren't the only ones with teeth too big for our mouths back in the day - and we're pretty sure we owned that skirt too.
We're hoping the actress is set to start a trend with this post. We could certainly get used to seeing LOL-worthy snaps of our favourite A-listers every time they want to give a big birthday shout out to their nearest and dearest.
However, in truth Amanda's not the first to get nostalgic on Instagram - fellow actress January Jones and superstar songstress Beyonce are both already big fans of posting old school snaps.
Earlier this year Mad Menstar January made a good case for never allowing your mum to cut your hair. A mixing bowl and a pair of scissors does not a hairdressers make.
On the other hand Queen Bey set out to prove she's always been painfully adorable. Some things never change. Siiiigh.
It seems we should all be on board with sharing blast from the past pictures. According to some, the process can even make you a better person.
But before you start rolling your eyes and tutting, perhaps you should watch this...
