Whether you call it #ThrowbackThursday or #FlashbackFriday you're probably well aware of the growing trend of posting old pictures on Instagram. We've had Kim Kardashian sharing pre-pregnancy pics, photos from Courtney Love's rock 'n' roll past and old Victoria's Secret modeling snaps - in fact, it seems like everyone's got pictures of their younger selves that they're eager to unveil. And what's not to like? The vintage filters are already built in!
Catwalk stars have some of the best archives to draw from so we've seen the likes of Alessandra Ambrosio, Chanel Iman and Coco Rocha posting images of their early shoots including Coco's first agency pics taken when she was a schoolgirl. While the Canadian model sports "long weirdly highlighted hair", Heidi Klum unearthed her punk past by tweeting a photo of herself aged nine with black lipstick and one half of her head dyed green and the other red.
Justin Timberlake's wifey Jessica Biel gave us all a blast from the past by reminiscing about her role in TV show 7th Heaven. She captioned a still from the series: "I'm pre pubescent, pissed & holding a dog. Happy #TBT & long live #7thHeaven!" Meanwhile the Kardashians have used #ThrowbackThursday as an opportunity to remind followers of their former figures - Kim before she got pregnant and Kourtney as inspiration to start running again.
It doesn't really matter to us if stars are reliving former glories or simply enjoying a trip down memory lane, we can't get enough of their retro photos.
Take a look through some of our faves in the gallery above...
