If you really think about it, the late '90s and early 2000s was a golden era for our favorite pop stars. Some of our current favorites got their start during this girl power era: Beyoncé was the face of Destiny's Child and had us all saying her name, and Britney Spears had us all singing the lyrics to 'Baby One More Time' way too often. But while these artists have been in the music business for years, most of them look just as stunning now as they did when they first hit the scene — if not better!

A few of them, however, have gone through some pretty shocking transformations. For instance, have you ever noticed that Ariana Grande's face has completely changed since her Nickelodeon days? Or did you know that Nicki Minaj appears to have a drastically different nose these days? (Yeah, it took us a while before we realized it, too.)

Take a trip down memory lane and see what your fave stars looked like in the good old days…
