The 36-year-old television personality - who has three-year-old daughter North and 15-month-old son Saint with her husband Kanye West - has made it known she is desperate to expand her brood, and it has been reported she has even sought sex and relationship tips from her 61-year-old mother to help her conceive.

A source told Closer magazine: "Knowing how much Kris went through to have six children, Kim's been turning to her for support and Kris has been giving her some great advice about preparing her body for pregnancy. She's been offering Kim guidance about what to eat, special workouts and methods to keep her stress levels at bay.

"Kris has been stressing the importance of a healthy sex life to Kim and has been giving her tips to spice things up such as role play and sexy nights away to get the spark back."

The 'Keeping Up With the Kardashians' star was originally "grossed out" by her mother's advice, but she has since realised it is will prove useful.

The source explained: "It grossed Kim out at first, but she realised how important her mum's advice was for the sake of her marriage and getting pregnant, which is her main goal."

The brunette beauty recently revealed she is contemplating surrogacy after she endured complications with the birth of her two kids.

Speaking previously about her future plans to have a third child, she said: "I'm definitely leaning more toward [surrogacy] I want to try it.

"After talking to Kanye, I think that I always knew that surrogacy was an option, but I didn't think it was that realistic of an option. Now, I feel like that's my reality.

"I feel like surrogacy really is the only other option for me."
