Kim Kardashian wants to take backseat in reality shows

The 31-year-old is having second thoughts about how much of her life is laid bare on 'Keeping Up With the Kardashians' since her relationship with rapper Kanye West is getting serious, reported Heat magazine.

"Kim has secretly been getting embarrassed about how much her family share and there's no way Kanye would allow the intimate moments of their relationship to be filmed. He is happy to be in the background, but he thinks some things should be kept private," a source said.

Kim married basketball player Kris Humphries in a lavish televised ceremony last year, only for the union to fail after just 72 days.

She is now said to agree with West's vision to market them as a couple rather than be so heavily involved with working alongside her mother and siblings.

"Kanye is thinking of their brand as a duo now, rather than her family's. He thinks some of what she's put her name to is tacky and has already advised her to say no to certain things," the source added.
