Kim Kardashian's mother, Kris Jenner, fears she is ''losing'' her to Kanye West.
Kris Jenner is worried her daughter's new relationship with the rapper is taking over her life and she may be willing to put him before her family.
A source told Hollywoodlife.com: ''Kris feels like she is losing Kim to Kayne and she is devastated. She never ever thought Kim would put a man before family, but that's what Kim is doing.
''Kris and Kayne have really strong personalities and like to be in control. Kim and all the girls are so used to Kris calling all the shots.
''I think deep down Kim likes having Kayne being in charge. She is used to that role because she grew up with such a controlling mother.''
Kanye has already reportedly had an effect on Kim's style, urging her to be more daring with her outfits.
A source said: ''He thinks she should be more like him, edgy with her choices.''
Subsequently Kim, 31, posted a racy snap of her in underwear and a biker jacket posing seductively to her Instagram account today (31.05.12), with the message: ''Thanks to all you two million sexy beasts out there for following me on Instagram! So here's a little present.''
The insider worries Kris - who is also mother to Kim's sisters Khloe and Kourtney, brother Rob and step-siblings Kylie and Kendall Jenner - could start using ''guilt trips'' in order to make Kim pay her family more attention.
The friend added: ''When Kris isn't in control she isn't happy and she puts a guilt trip on her daughters, especially Kim right now, that family loyalty comes first! Even before your husband or boyfriend.''
