The 10-Year Challenge or the How Hard Did Aging Hit You Challenge, whatever you want to call it, is simple: You post a photo of yourself in 2009 next to a photo of yourself in 2019.
As the first real trend of 2019, it truly has taken over the Internet and we wanted in on the action.
All weekend, get ready to flash back to 2009 with nothing but songs from 10 years ago!
Enjoy a weekend full of nostalgia and some of our favorite 10 year challenge photos below.
