WATCH: Kylie Jenner vents to her sister about Kim copying her

Los Angeles - Kim Kardashian West is "cramping" Kylie Jenner's style.

The 17-year-old reality TV star thinks her older half-sister, 34, copies all of her ideas and makes them "way cooler."

The teenager vents her frustration to Kourtney Kardashian in a deleted scene from an upcoming episode of Keeping Up with the Kardashians, saying: "I really feel like Kim is cramping my style.

"I feel like style-wise, we take things from each other. I did this dessert photo-shoot and now she's doing a dessert photo-shoot. She does takes everything and does it way cooler."

When Kourtney, 36, asks why she hasn't confronted Kim, Kylie replies: "Because I don't want to be annoying.

"And then now she has short hair... Well, I have short hair, but I have a weave in.

"Maybe she just wants to do everything I do."

Kourtney claims Kim used to be "super competitive" when they were younger and Kylie says: "I think she still is."

Kylie, who is dating 25-year-old rapper Tyga, previously named Kim and her husband Kanye West as her biggest style icons.

She said: "The people who really inspire my style-wise are obviously Kim and Kanye."
