Stop what you're doing!
North West finally has a sibling!
Kim Kardashian West is officially a mommy for the second time, giving birth to a healthy baby boy on Saturday morning, December 5!
OH EM GEEE — daddy Kanye West must be over-the-moon excited with their new arrival!
"Kim Kardashian West and Kanye West welcomed the arrival of their son this morning. Mother and son are doing well."
Ever since we heard the news of Kimmy's latest pregnancy back in May, we've been waiting for this moment. We're just so thrilled for this whole family!
Now all that's left is for Kim and Kanye to reveal the name of their bundle of joy!
And, you know, that whole push present thing. LOLz!
Seriously though, congrats to this family of four!!
