The 17-year-old was across the pond at a photo call for Nip+Fab and had her family makeup artist and BFF Rob Scheppy get her red carpet ready, but his attempts at cleavage contouring failed. While Kylie's face looks fab (we're loving the red lip), you can see obvious makeup lines between her neck and boobs. It seems the makeup artist was trying to enhance her bust line by applying a bronzer on top, but he forgot to blend which became obvious when cameras flashed.
Hey, it happens and despite the makeup mishap, Kylie had a great time promoting the beauty line, which she just became an ambassador for. See more from Kylie's London trip below!
