In case you haven't noticed, almost everyone is doing the #PubertyChallenge on social media these days. Even some celebrities have participated in this trend. It's basically uploading side-by-side pictures of yourself from before and after you hit puberty, which shows how much you've changed through the years. It's quite entertaining really because we never thought some of the people we know looked that cute and adorable when they were younger! Just take a look at these #PubertyChallenge photos we've made for your favorite Korean stars...so you won't have to anymore!
