THE TONIGHT SHOW
This is a gif set featuring Katy Perry, on the late night television show "The Tonight Show with Jimmy Fallon". wearing a sparkly outfit that blew my mind because it was nearly a perfect illusion of a starry night sky.
Season 4, Episode 153:
"Katy Perry (album "Witness", Saturday Night Live: Dwayne Johnson/Katy Perry (2017)); Josh Charles (The Drowning (2016), off-Broadway play "The Antipodes"). Also: Al Madrigal performs stand-up."
