Kylie Jenner's is going too far with surgery.

The 17-year-old star is the youngest sibling of half-sisters Kim, Kourtney and Khloé Kardashian, and rose to fame with her family on reality TV show Keeping Up with the Kardashians.

While the older women were the original attraction, Kendall a successful career as a fashion model.

Kylie is just as prolific, although those close to her are said to be worrying about her apparent cosmetic surgery procedures - something she vehemently denies.

Kylie Jenner's friends are reportedly trying to convince her she's going too far with surgery.

"She's convinced her lips can set her apart from her sisters and even has plans to launch her own make-up range one day, but in the meantime her friends are trying to convince her she's going way too far. If someone doesn't step in, she could end up like those child stars who have taken surgery too far and have been through the mill emotionally and physically," an insider told British magazine Now.

Kylie has been rocking a plumped-up pout, but claims it is all down to clever make-up and not surgery.

However, others have commented on her frozen face recently, claiming her arched eyebrows have the tell-tale signs of Botox.

"It's turning into a joke. There are rumours that she has had work done but she doesn't think it's a big deal and can't understand what all the fuss is about. Yes, she's denied it, but growing up in her family, having a boob lift it's as normal as a cleanse, tone, moisturise," the source added.
