Kim Kardashian West and her newborn son have left the hospital.

The Keeping Up With The Kardashians star and her three-day old son Saint made a quiet exit from the Cedars-Sinai Medical Centre in Los Angeles yesterday and are now relaxing at Kris Jenner's home, whilst their house is being renovated.

A source told Us Weekly magazine: "They are so ecstatic. Kim and Kanye are both so happy he's here, and Nori is already in love."

There have not been any photos of the newborn released, but Kim did post an emoji of her growing family, along with the child's name on social media yesterday.

Meanwhile, the 35-year-old television personality - who also has two-year-old daughter North - had a "really tough" pregnancy because of her placenta accreta condition, where the placenta fails to detach from the womb.

An insider shared: "She had a really tough birth because of the issues with her placenta."

"And it hasn't just been the final part of the pregnancy that has been difficult for Kim, as she previously revealed she had to have an External Cephalic Version to have her baby moved from the breech position."

Khloé Kardashian previously posted a video saying Saint is "perfect".

She is reportedly besotted with tiny tot and couldn't help but brag about his sweet features when she sat down for a live stream with her fans on her website.

She said in the short black-and-white video clip: "My little nephew was born he is so cute and so perfect. I love him and mommy and daddy are doing fantastic."
