We're coming to the end of the last decade, and soon we'll be entering 2020. It's a new decade: a time for reflection and introspection, to look back at what has passed us by. A whole lot has changed over the last ten years when you think about it. We're all a bit older, we're all a bit wiser, and some of us look completely different. Lately, plenty of people have been playing the 10-year challenge, where they compare pictures of themselves from a decade ago to images of themselves nowadays, to see how much they've changed.
Indeed, even our favorite celebrities have changed a lot. No really, they have! The ones who were pint-sized are now all grown up, while the ones who were adults already might have changed their style or look. You might not have realized just how much a lot of them have changed, but believe me: they have. Scroll down to check out some side-by-side pics of how much celebrities have changed since 2010.
