It has been alleged that Kim Kardashian and rapper husband Kanye West rarely have sex these days.

The reality star bragged to her sisters during the 10th season premiere of "Keeping Up with the Kardashians," when she said, "I've been having sex 500 times a day."

It turns out, Kardashian was more than hyperbolizing. A source alleged to OK! Magazine that the relationship is not as strong as it appears on the show.

"They might talk the talk, but they're lucky if they have sex once a week," the source said.

The A-lister couple's lack of sex is supposedly due to their hectic work schedules.

"Things have been so tense between them, and Kanye's completely exhausted because of all these new projects he's got on the go, so Kim's getting frustrated," the source continued.

As a result, the "KUWTK" star, who has "a huge sex drive," reportedly plans to hire "a sex 'whisperer' -- type therapist to fix the problem" and improve her sex life with the Chicago emcee.

Also, it is possible for the sex therapist to be featured in the E! reality show, as "Kim wants to include some of their sessions in 'KUWTK' storyline."

The source added that the pair is only inspired to have sex when Kardashian is ovulating, as they are making every effort to give their baby daughter, North West, a sibling.

"It's so frustrating. Kourtney just sneezes and gets pregnant. Like, not everyone is like that," Kim said. "It's going to take work, and I have to work hard at it."

In addition, there have been rumors of the two possibly divorcing. But if this news is true, it is still not happening. A source alleges that because of their careers the two will not be divorcing.

Celeb Dirty Laundry recently alleged that Kardashian and Yeezy were "ready to sign the divorce papers."

Their "marriage is as good as over," since they have supposedly been fighting for months over family drama, as well as rumors that West has not been faithful. The infertility issues is just another problem the two have faced. ,

However, after realizing that "without Kimye, their images would be dead in the water," the couple is currently staying together for fame, allegedly.

"Kanye is loving his and Kim's new business arrangement," an insider revealed. "At first, he was skeptical but now, it's fun for him -- that's why he was all over her at Paris Fashion Week and way more affectionate than usual."
