Who doesn't love a good #TBT? We look back - literally - at the best of the celebrity throwbacks. The ones that made us LOL, aww, and miss the good 'ol days...
We love a good celebrity throwback picture. You can say what you like about social media and the modern world's supposed addiction but our favourite social platforms have given us a great many things - not least, the celebrity #TBTs.
Yes #ThrowbackThursday, #TBT, #FlashbackFriday or #FBF - if you will - have meant that some of the most marvellous images of the A-List have been unearthed deep from within the archives: From the stars' first time on a film set, to their family photos to their hilarious reactions now to past fashion faux pas, #TBT is the hashtag that keeps on giving.
There's also more than a spattering of awkward school photos (hey, we've all been there), through a few unbelievably uncoordinated fashion trends to seeing future A-listers meet their besties for the first time - a picture really does say a thousand words and takes us right back to times gone by.
Indeed, when celebrating Kate Moss' 42nd birthday, her longtime pal Sadie Frost took to Instagram - as you do in 2016, right? - posting a photo wishing Kate a happy birthday and nodding to some of their best images from the 90s.
Or what about Eva Mendes' throwback to her cameo in Will Smith's Miami music video? How else would we remember that the Hitch co-stars previously worked together - in a music video, no less.
And let us not forget the baby photos. It seems the celebs can't stop themselves from posting the awkward, hilarious and downright A-dorable throwbacks to their childhood, usually poking fun at their lack of fashion savvy or uncontrollable facial expressions (we're looking at you Taylor Swift).
Since we can't get enough of these fabulous blasts from the pasts, we've rounded up the very best of celebrity #TBTs, #FBFs and generally great throwback Instas...
