See Reese Witherspoon, Nicki Minaj, Jessica Biel and More Take The 10-Year Challenge!

Ever wonder what the most attractive people in Hollywood looked like 10 years ago? Well, thanks to the Instagram Gods, wonder no more!

Our favorite stars are hitting the gram to flex their beauty with side-to-side comparisons a whole decade later for the #10YearChallenge.

While most of them look nearly identical as their younger selfs (we're looking at you, Reese Witherspoon, Jessica Biel and Kevin Hart), some celebrities have really upped their A game.

P!nk has gotten out of her punk stage, Nicki Minaj has really learned to flaunt her curves and J Lo has gone from pregnant with twins to the smoking hot vixen she is.

It's super fun to see celebrities hitting the #10YearChallenge, but one family we'll bet on who won't be taking the plunge isthe Kardashians.

So, here's a mock up we created to compare the reality stars to their 2008 selfs. And while we're at it, here's the Jenner sisters and mom Kris too. Of course, none of them are as good as Caitlyn Jenner's actual entry for her transformation photo.
