Kim Kardashian West
Kim Kardashian West is jealous of Kylie Jenner.
The 34-year-old television personality is reportedly worried about her half-sister becoming a "better-looking version" of her.
A source shared: "Kim's been moaning to her mom for months now that Kylie's slowly morphing into a better-looking version of her - and she's not happy about it."
She was so upset she even confronted the 17-year-old television personality about stealing her style but Kylie completely "denied" it.
The source added to US' OK! magazine: "She fronted up Kylie and tore into her for copying her style and her look. Kylie denied it, of course, but she really does look more like Kim every day...
"Kim's got a huge ego and thinks Kylie's a threat to her brand... It's because Kylie's a much better looking version of her - and she knows it."
This comes just days after it was reported that Kylie is looking to outshine her older half-sister by going into the music business.
The insider shared: ''If Kylie feels competitive with anyone it's Kim. She feels they have similar body types and looks. Kim is doing modelling, fashion, television and much more which is exactly what Kylie wants. She doesn't want to be put in a box and only do one thing.
"She wants to be like Kim, but even bigger and more diverse - getting into music and producing as well."
