Kendall and Kylie Jenner want to quit 'Keeping Up with the Kardashians'.

The sisters are reportedly eager to leave the show when their contracts expire and launch their own brand together.

A source told RadarOnline.com: ''Kendall and Kylie have both wanted out of 'KUWTK' for quite some time now and they are starting to realise their power because people are focusing on the two of them more than ever before.

''The know that they are hot right now and that is why they are constantly together.''

Kendall, 19, and Kylie, 18, were thrust into the spotlight when the E! reality show launched in 2007.

It's thought the young Jenners have found it difficult opening up about their father Caitlyn Jenner's transgender transition on TV and want to have more control over their careers.

The insider added: ''Kylie does not want to ever leave television, but she does want to separate herself from the current storyline of the show.

''Caitlyn's transition has been really hard on her and neither her nor her sister like the fact that they have to talk about the hardest thing that they have ever had to go through on TV.''

Kylie is said to be considering her own spin-off show, while Kendall has become one of fashion's biggest it-girls with a burgeoning modelling career.
