While most of us are busily hiding evidence of what we looked like the '80s, Katy Perry is happily revisiting the decade known for its love affair with blue mascara for her latest cover artwork for the single “Last Friday Night (T.G.I.F.),” the fifth track to come off of her Teenage Dream album. Teaming her neon triangle earrings with some full-on blue shadow and standard '80s issue fronted pink lipstick, Katy even shows off some braces on her teeth. What do you think of her latest look? We're not sure what the team at ghd would think of their newly-signed ambassador's frizzy curls! To hear the song, head over to PopSugar and tell us your thoughts!
