The KKW Beauty founder announced their baby's arrival with a simple message on Twitter, after Kourtney Kardashian revealed on Thursday, May 9, that their surrogate had gone into labor. They confirmed in January that they were expecting another child, and Kim has already been preparing herself to have her hands full balancing a newborn, her other three children, her husband, and her career.

Kim confirmed the news in the most simple way.

Kim skipped the usual fanfare, and instead she took to Twitter on Friday, May 10, to send a quick and simple message to fans about her baby. "He’s here and he’s perfect!" she wrote. This is the couple's fourth child and second son. This is also the second child they have had via surrogacy; daughter Chicago was born via surrogate in January 2018. Kim also tweeted: "He’s also Chicago’s twin lol I’m sure he will change a lot but now he looks just like her.✨"

Kardashian and Kanye fans have been on baby watch all week.

While the royal baby was born earlier this week, it was reported that Kim and Kanye were also due this week. A false report surfaced on Monday, May 6, that the baby was already born after Kim shared a screenshot of a text from her husband that read that she was a mother of four. But now it's official. The West clan is now a family of six!

Big sister Kourtney Kardashian spilled the beans on "The Ellen DeGeneres Show."

Kourtney surprised her mom, Kris Jenner, for Mother's Day on the show, which aired on Thursday, May 9, by bringing out six of her grandchildren during her appearance. Kourt was on babysitting duty with Kim's three kids–North, Saint, and Chicago–and said her little sister was not in attendance because her surrogate had gone into labor!

Kim has her hands full now that her fourth baby is here.

On a recent episode of Keeping Up With the Kardashians, Kanye and Kim spoke about how busy she would be while taking care of a newborn and pursuing a law degree, but he was fully supportive of her decision. Kim has taken on a lot, but there's no doubt that she'll be able to handle her empire, her family, and her new passion and goal to become a lawyer. Congratulations to the happy family!
