A boy she kissed with told Kylie that she was a “good kisser” but had “very thin” lips.

The Keeping Up With The Kardashian star opened up about her beauty insecurities during her interview with TV show host Andy Cohen.

The makeup mogul was quoted as saying, “I think my love of makeup started with my insecurity with my lips.”

“I had very small lips and I never thought about that until I had one of my first kisses and a guy said to me, ‘Oh my God, you’re such a good kisser but you have such small lips’ or something like that.”

‚ÄúSince then I felt impossible to kiss. I was insecure because this guy said something to me once. I became obsessed with makeup because it delineated my lips and made me feel confident. “
