Kim Kardashian and Kanye West are preparing to welcome their third child. According to TMZ, a surrogate hired by the reality star and her rapper husband is already three months pregnant.

An insider told the publication that the superstar couple has agreed to pay $45,000 (£34,000) in 10 monthly instalments of $4,500 to the unidentified woman from San Diego. Should there be more than one child, Kardashian and West pay $5,000 per additional child.

Other stipulations outlined in the contract are no drinking, smoking or drug use; no hot tubs or saunas; no raw fish; and no handling cat litter.

They are said to have found the surrogate, who is in her late 20s, via an agency and paid $68,850 for the service.

Kardashian, who suffered from placenta accreta − a potentially life-threatening condition which sees parts of the placenta grow too deeply into the uterine wall − during her two pregnancies had made no secret of her desire to expand her brood.

Discussing her pregnancy struggles with her sister Khloe during an episode of Keeping Up With The Kardashians in 2015, she said: "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 is really the only other option for me."

Meanwhile, Kardashian has put an end to her feud with Caitlyn Jenner to join her estranged family member in condemning President Donald Trump's decision to ban transgender people from serving in the military.

Jenner, who is Karadhian's stepparent, slammed the US president for going back on his word to support the LGBT community. The transgender star tweeted: "There are 15,000 patriotic transgender Americans in the US military fighting for all of us. What happened to your promise to fight for them?"

Kardashian chimed in by calling the move, which reverses an Obama-era policy, as "simply wrong". She said: "Banning transgender people from serving our country is simply wrong. We should be so grateful to anybody who wants to serve!"
