Following the birth of Saint, Kim spoke candidly on Keeping Up With the Kardashians about wanting another baby, however, the reality TV star had been diagnosed with placenta accreta, which meant a third pregnancy would pose an extremely high risk to her health.
"I can’t carry anymore kids … it’s the worst," she said on the show. "It’s not going to be happy for me.. I had a full break down … I give up."
"So now I want to explore surrogacy," Kim went on to tell her mum, Kris Jenner.
According to TMZ, the couple will pay the unknown surrogate $US45,000 ($59,000) in $US4500 ($5900) monthly installments to carry their baby.
