Bound 2 hitmaker Kanye West reportedly wants to turn Kim Kardashian into the ''perfect'' wife.
The 37-year-old rapper is said to advise his wife on how to behave when they are out together.
Speaking to Grazia magazine, a source said: ''Kanye can be very controlling with everything in his life, that's his personality. He wants Kim to be perfect.
''In the old days, you'd always see Kim smiling when she was having her photo taken. But now, more often than not, she'll be stony-faced.''
They added: ''It seems even when he's not around she can't make decisions. Kim will call him to check she's buying the right brand of water. She can't even pick her own nail varnish without checking with him.''
