Kim Kardashian wants to have a third child with Kanye West Reuters

Kim Kardashian and Kanye West are fighting over having a third baby. The couple are apparently arguing over their surrogate baby plans.

A source told Radar Online: "Kim is pressing the issue more than ever now and thinks that another kid will save their marriage, but she and Kanye can't agree on anything involved in this process."

"They are really trying to figure out what type of contract their choice for surrogate will sign, but Kim has made it clear that she will pretty much pay anything for another baby," the insider added.

"In addition to offering their surrogate a six-figure deal, they will also make sure she has full security and benefits and that she is spoiled and pampered the entire time!" the source revealed.

The Keeping Up With The Kardashians star - who has daughter North West and son Saint West with husband Kanye, had two really difficult pregnancies.

During an episode of Keeping Up With the Kardashians, the 36-year-old reality star talked about expanding her family. She said to her sisters, Kourtney Kardashian and Khloe Kardashian and her mother, Kris Jenner: "I'm going to try to have one more baby."

"I want my kids to have siblings but the doctors don't feel like it's safe for me," Kim added.

However, the Kardashian matriarch said: "I don't want you to do something that would put you in danger."
