The reality star, 35, has given birth to a healthy baby boy on Saturday morning with her rapper hubby by her side.
The proud mum announced the arrival on website, writing, โKANYE AND I WELCOME OUR BABY BOY!โ
โMother and son are doing well,โ the message stated.
Although the bub was believed to be due around Christmas Day, he is said to be doing well.
The day earlier, Kim had posted on social media a selfie showing her baby bump, saying, โReady whenever you are lol.โ
Bub number two will join two-year-old big sister North West, who was born on June 15, 2013.
Although the new arrival hasnโt been named yet, Kim has previously revealed that she liked the name Easton, which is certainly keeping with the compass theme of her growing family.

Kim also shared this sweet photo with the announcement of the birth.
The world is also eagerly anticipating the first photos of Kimyeโs son, after North Westโs debut was made two months after her birth on proud grandma, Kris Jennerโs former talk show.
In true Kardashian style the fashion icon revealed her pregnancy on the familyโs reality show Keeping up with the Kardashians in June.
It hasnโt been an easy road to conception, with Kim being open about her harrowing fertility struggles.

Kimโs pregnancy didnโt stop her from serving up some fierce fashion this year.
โItโs been really emotionalโฆ there are definitely times when I walked out [of the doctorโs office] hysterically crying,โ she told Glamour magazine.
Kim even revealed on the show that sheโs been so desperate for a second baby that she and hubby Kanye have been โhaving sex 500 times a day,โ โ now thatโs dedication!
Before falling pregnant a frustrated Kim told the cameras, โIโm, like, so over it [trying to conceive]. Like Iโm exhausted, so Iโm sure everyone gets to that point. Iโm like, โokay, Iโm done.'โ

Three have become four! North will no doubt be a doting big sister to her baby brother.
But all that work has finally paid off, with the best kind of reward.
Despite the blessing, Kim had a difficult second pregnancy. โI just donโt think pregnancy and me really agree with each other. You know, it was really hard for me to get pregnant so I do feel really blessed that I am pregnant and, at the end of the day, it is a million times worth it,โ she told E! News in November.
โIโm really not complaining, Iโm just being honest and being honest about [it]. I hate it. You know, pregnancy is not for me. Iโve heard stories forever about how amazing pregnancy is from my mum and Kourtney and thatโs just not the case for me, and Iโm not going to sit here and lie and act like itโs the most blissful experience. Itโs awful.โ

This new baby is only a year younger than his cousin Reign Disick, meaning theyโll have a close bond just like North and Penelope Disick โ Kourtney Kardashianโs middle child โ who have the exact same age gap!
However, Kim admits the pain is a fair trade off and she loves every second of motherhood.
โI used to enjoy the spotlight. If I had a day off from filming, I didnโt know what to do. Now I enjoy my family time so much, there is this sense of, if it all went away, and I was just a mum, I would love my life,โ she mused.
Congratulations Kim and Kanye, enjoy the newest addition to your stylish family!
