Kim Kardashian and Kanye West have welcomed their baby boy.

Their little bundle of joy was delivered on Saturday morning (05Dec15) without complications, a week after Kim underwent a medical procedure to turn her breech baby around.

The new parents have yet to reveal a name, but the reality TV star was quick to post the happy news on her website.

"KANYE AND I WELCOME OUR BABY BOY!" she wrote excitedly.

Kim also took to Twitter, writing, “He’s here!”, alongside a touching snap of her holding hands with Kanye.

“Kim Kardashian West and Kanye West welcomed the arrival of their son this morning. Mother and son are doing well,” a statement on her website confirms.

Their son is a baby brother for two-year-old North. Just like their daughter, the baby was born a little early, as Kim was reportedly due to give birth on Christmas Day (25Dec15).

It seemed the star was getting impatient, as she posted a picture to her Twitter page on Friday (04Dec15), showing off her big baby bump while wearing a sports bra.

“Ready whenever you are lol (laugh out loud),” she informed her baby.

Kim and Kanye wed last year (14).
