Kim Kardashian Gives Birth To A Boy! 2nd Baby For Star And Kanye West

North West is a big sister now!

It's official: Kim Kardashian West and Kanye West welcomed baby no. 2 into the world Saturday morning!

Reality TV star Kardashian West announced the birth on her website the same day. No name yet for the littlest West, but "mother and son are doing well."

The newest arrival means the celebrity couple's daughter, 2-year-old North (aka Nori) West, is a big sister now. Only a few hours before the announcement was made, Kim posted a photo of herself on Instagram, with the caption, "Ready whenever you are lol"

Reality TV star Kardashian West had posted recently on her site that the baby was the size of a pumpkin and that her "cankles were out of control." Guess the baby listened to his mama and decided it was high time to make an appearance!

It's not too much of a surprise the baby's name hasn't been announced yet. Kim told E Online in November that she and superstar musician husband Kanye had not chosen names. "We just started talking about it and that was the last thing for us last time. So I feel confident obviously that we'll figure it out," she said.

We have a feeling that whatever name they choose, it will be far from ordinary. Congrats, Kim and Kanye! We wait with baited breath for the first photos.
