Kanye West is interfering with Kim Kardashian's new clothing line.

The 32-year-old brunette beauty is reportedly working on a range of children's clothes and although the 'New Slaves' hitmaker has encouraged her, he is worried about how the final designs will look.

An insider told RadarOnline.com: ''He opened doors for her where they were once shut, which is great, but now he's giving her his two cents on everything and it's driving Kim crazy.

''The truth of the matter is he doesn't think Kim has good style and he knows whatever she produces will be a direct reflection on him. He doesn't trust her to do her own thing.''

Kim - who has three-month-old daughter North with the rapper - was catapulted into the spotlight with her reality TV show 'Keeping Up With The Kardashians', but her boyfriend is hoping to reimagine her as a fashion designer.

The source continued: ''Kanye encouraged her to pursue her own baby clothes line. He thought it was a great way for her to be taken a little more seriously and cut the cord with her family. He wants her to establish a new career away from reality TV and this is how they think she can do it.''
