Katy Perry is clearly a '90s kid -- and she has the nail art to prove it!
The singer tweeted a pic of her impressive fingertips today, showing each nail elaborately painted with faces of the characters from "Daria."
"It doesn't get any better than hand painted DARIA nails by the girls at ES Nails TOKYO," Katy posted along with the pic -- which show the title character, BFF Jane, Trent, Quinn, Brittany, Jodie, Chuck, Kevin and Fashion Club secretary Stacy Rowe.
This are by far some of the coolest nail art we've seen in a while ... and Katy's got some stuff competition.
