It’s time! Kim Kardashian goes into labor with her son, Saint West, during the upcoming season 11 Keeping Up With the Kardashians finale. In a sneak peek of the Sunday, February 21, episode, the reality personality is about to become a mother of two.

“My water just broke,” Kardashian, 35, tells her mom, Kris Jenner, in the dramatic teaser. “What!” Jenner exclaims.

In another sneak peek of Sunday’s episode, Kanye West’s wife reveals just how nervous she was to give birth to her second child, whom she welcomed into the world on December 5.

“I can’t even begin to explain the anxiety that you have when you just don’t know when you’re gonna go into labor,” North West’s mom tells the camera. “They always say your second baby comes quicker, so I just hope I make it there in time. … The unknown just scares me.”

“He’s here!” she announced at the time on Twitter, along with a sweet photo of herself holding Kanye’s hand. "Kim Kardashian West and Kanye West welcomed the arrival of their son this morning," a statement on her site also read. "Mother and son are doing well."

Kardashian and West have yet to share a photo of their son’s face. Kardashian posted a photo of his teeny hand last month.

Watch the clip above. The season 11 finale of Keeping Up With the Kardashians airs on E! on Sunday at 9 p.m. EST.
