Kim Kardashian and Kanye West have named their fourth child Psalm The news was announced in a Twitter post with a picture of their new son, Kim wrote: "We are blessed beyond measure. We have everything we need."
Just after the baby's birth by a surrogate Kim, 38, tweeted how perfect her new son was. "He's also Chicago's twin lol I'm sure he will change a lot but now he looks just like her," Kim wrote.
Psalm or the book of Psalms appears in the old testament of the Bible and means "sacred song" or ”hymn”.
The celebrity couple, who have been married for almost five years, already have three children called North, Saint and Chicago.
During an appearance on Jimmy Kimmel Live in the US Kim was asked about baby names and said she had been googling Armenian boys' names but couldn't really find anything.
She then added: "I was truthfully thinking about just naming him Rob, my brother Rob, but then it's like, North, Saint, Chicago, Rob - it doesn't really go."

"Rob would have been a more normal name but all other three siblings have special names," naming expert Marc Hauser tells Radio 1 Newsbeat.
His thoughts on Psalm: [Huge pause] "It's short...but it's nice."
"The problem comes when it comes to mean something from the Bible. A first name shouldn't be a statement in religious terms," he adds.
"In an international environment religion should be something private as it could have an adverse affect," Marc adds.
"You could meet anyone of any religion. If your name is Jesus or Muhammad - I'm not sure a religious statement should be the first statement you make."
"North is north for everyone, no matter what religion," says naming expert Marc Hauser
"I like North best. Geographical names are perfect. It's a good meaning, helps you navigate in your life and fits well with their surname.
"But Psalm doesn't feel such a perfect fit. It takes a lot of courage to invent a new name. They've made some good choices but perhaps not in this case."
