Kendall Jenner thinks sister Kylie would make a ''sick'' men's fashion line.

The 'Keeping Up With The Kardashians' star - who has teamed up with her 18-year-old sibling for a number of fashion and beauty endeavours - thinks Kylie would be a great person to lead a new clothing line for men.

Whilst stepsister Kourtney Kardashian suggested the sisters should ''leave it up'' to Kanye West, Kim Kardashian's husband, Kendall said: ''Kylie would make a sick guy's line, I feel.''

And the 19-year-old model - who is just one of the family to recently release her own website and smartphone app, which offers fans beauty and fashion advice as well as an insight into their lives - has insisted that the similarities between their final products are a result of their ''blood'' connection.

Speaking at an Apple Store in New York City, she shared: ''I got in a fight with my manager because I wanted to see Kylie's boards so long ago and she literally wouldn't let me see her board. It's crazy how they're similar.''

Whilst Khloe Kardashian added: ''When we all saw them collectively, they all kind of emulated each other. It's kind of the blood with the sisters, I guess.''
