Kanye West has reportedly advised Kylie Jenner to stop dressing like wife Kim Kardashian West.

The 'All Day' rapper is a big supporter of Kim's half-sister and thinks she has great ''potential'' to become a superstar in her own right so he told her to ''create her own identity'' rather than copy Kim's style.

A source told HollywooLife.com: ''Kanye is Kylie's biggest supporter and loves the young lady she is becoming. He's definitely been championing her for years as he sees real superstar potential in Kylie. That's why he felt OK telling her that she needs to stop copying every move Kim makes and create her own identity.''

Kylie - who turns 18 next Monday (10.08.15) - paid attention to her brother-in-law's advice but admitted she can't help but be inspired by Kim's look because she respects her fashion sense so much.

The source added: ''Kanye worships Kim and he has told Kylie there can only be one of her. Kylie hears what he's saying but honestly, (she) doesn't know where to take her look at this point. She's digging her looks and style and doesn't really care if she's stepping on Kim's toes a little.''
