Jenner, 17, set the record straight at the Kylie Hair Kouture party at James Kendall Salon in Beverly Hills, reported E!Online.
"I feel like everyone has been talking about it for months, so I'm kind of sick of it. My pictures, I palp them out a lot. I think big lips are awesome," she said.
Fans of her first noticed a plumper pout last month in a series of Instagram posts.
The 'Keeping Up with the Kardashians' star does not bother what people think about her.
