That is definitely a lip ring Penelope Disick is wearing in the photo posted by mum Kourtney Kardashian.
Apparently, Kim Kardashian gifted her niece with one so they could look alike. Even if it is fake, people are still claiming it to be inappropriate for a 4-year-old to wear one.
"Little to young for a lip ring" and "WHAT DO PEOPLE PORTRAY WITH THESE RINGS, THINK SHAME ON YOU" and "Isnt she too young for that smh".
Tbh we're 99% sure it's fake, like one of those old school magnet ones, so unlike most of the comments we reckon this kinda thing is pretty harmless.
