Isn't it amazing how much our favourite celebrities have changed over the past few years? Despite having some of the most easily-recognisable facial features in the world, they still manage to look so completely different after a couple of years that it's easy to forget what they looked like when their career was just getting started. For instance, just the other week I re-watched Titanic, and even though it was the movie that made its two stars famous, (and it doesn't feel that long ago that it was released in movie theatres) Leo and Kate Winslet still manage to look shockingly baby-faced: much younger than we're used to now. In the old days, pictures of their cute childhoods and blunder years of adolescence would remain buried, never to be seen by even the most dedicated of archivists. But thanks to the power of social media - Instagram in particular - it's never been easier for the stars to share their fondest throwback photographs for their many adoring fans. So, if you fancy taking a trip down memory lane, then scroll down to check out some of the most nostalgic examples we could find. 1.
