Fun Fact: All Your Favorite Celebs Looked Very Different at the First Teen Choice Awards — in 1999!

Ah, 1999 — what a different time that was! Everyone's pants were tighter, their tops were shorter, and there was no such thing as too much makeup or hair product. We have evidence straight ahead, from the first-ever Teen Choice Awards that year, held in Santa Monica, CA.

Those were the Latin explosion days, too — when we were all singing "Genie in a Bottle" before Christina Aguilera was Xtina and getting down to Jennifer Lopez's "If You Had My Love." And that means all your favorite Latino stars were on the red carpet. As you get ready to tune in to the 2017 award show look ahead to see what they wore, who they were dating, and how different they looked.
