As if we all need reminding of how much things have changed since 2013 – LOL.
But in case you can't quite remember what it was like to listen to a perky pop song back in the much less depressing early 2010's, maybe these pics of your favorite pop artists, all fresh-faced and dewy eyed, will remind you. Honestly, I hope these celeb lookbacks will bring you so back to 2013 so hard that you end up actually going back in time and warning us all.
Shoulda just stayed then…
