I think Jenner tried to trademark it as a brand name, for Kylie Cosmetics, several years ago. Minogue countered, won, and then released her own cosmetics branded “Kylie”, which I’m guessing flopped? Crazy to think how famous Minogue is in the U.K. and Australia when she’s C-list at best in the USA. Although I suspect her popularity is waning even internationally. I noticed she only has 2 million Instagram followers, despite being very active on the app for years.
