Kim Kardashian and Kanye West's one-year-old daughter North West may have a long wait for a sibling to play with.

According to a report published on RadarOnline, the couple have been clashing ever since their honeymoon and have put their baby plans on hold due to "constant fights" over balancing family time with their busy careers.

The famous couple "are having constant fights over the timing of having another baby," an insider told the news site.

The Kardashian star, who enjoys a close relationship with her sisters, has made no secret for her desire to get pregnant right away with another baby as she wants North to grow up with a sibling to play with.

West on the other hand is said to be resisting because he is going on a world wide tour after the release of his upcoming album and does not feel it is the right time.

"The couple doesn't even have their own house to live in! It's just too much chaos for Kanye to handle", the source said.

"He loves being a dad to their daughter, North, but having another baby would just push him over the edge.

"It doesn't help that the couple have been fighting a lot ever since they got married. Kanye who enjoys going to museums can't understand Kim's love of just lounging around for days at a time," as she recently did during a vacation at Joe Francis' Punta Mita mansion.

Not only did Kardashian relish doing nothing for days, the source said, but also, "She has even hinted that they should buy their own seaside getaway."

The report follows repeated rumours that Kardashian has been "unhappy" since marrying the Yeezus rapper in a lavish ceremony in May.

"By all appearances, Kim looks like she has it all, a perfect husband, and a beautiful daughter, but everyone can see the light and joy in her eyes is gone," a source told Radar.

But despite her marriage troubles, the Keeping Up with the Kardashians star "is absolutely determined to get pregnant," the source said. "And Kanye can never say to no to her in the bedroom. Their sex life is over the top, and Kim is boasting it's only a matter of time until she is pregnant again, so stay tuned."
