And the American songstress set tongues wagging once again with the most bizarre look we've seen in a long time!
The 'Crazy Kids' singer stopped by the BBC Radio 1 Studios in London this morning (12 July) sporting sore looking eyes, loaded with red eyeshadow and oodles of glitter.
She teamed her head-turning peepers with iridescent flower sequins floating around her eye, along with odd green bars running along her cheekbone.
To top it all off? A disastrous headband, paler-than-pale pink lippy and a gold tooth.
While we admire her bravery, this is one beauty blunder we won't be copying, like, ever!
