While older sisters Kim and Khloe Kardashian are supportive of the 17-year-old’s decision, Kendall, 19, isn’t a fan.
During a teaser for the latest episode of Keeping Up With The Kardashians, Kylie admits that her supermodel sister said her lips ‘look too big’.
Luckily Kim, 34, has some kind words for Kylie. “Your lips look amazing,” she tells her.
But she does have some sisterly advice: “I don’t want you to get carried away, lips aren’t permanent, but if they [reporters] ask about your lips, own up to it.”
KUWTK is filmed about six months in advance so it doesn’t look like Kylie followed Kim’s advice – she denied having help with her lips on more than one occasion this year.
Speaking to Grazia April, Kylie said: “I’m like, ‘Stop talking about my lips!’
“I haven’t had plastic surgery. I’ve never been under the knife. People flashback to pictures of me when I was 12 and say ‘Kylie’s so different’ but how can I look the same from 12-18?”
But Kendall did have some wise words for all of her sisters. She told them: “I don’t know why you guys are freaking out or talking about this? No one needs anything. Everybody looks beautiful.”
That’s a lot easier to say when you’re a model for the likes of Chanel and Calvin Klein, isn’t it?
However Kim disagreed and added: “No, I think if something makes you insecure and you’ve been feeling that way forever – who doesn’t want to look amazing? Do what makes you happy.”
Do you agree with Kim – should you change something about your body if you’re not happy, or should you learn to love yourself?
