The reality star revealed that she’s pregnant with the second child in a teaser at the end of the mid-season finale for “Keeping Up with the Kardashians” on Sunday night.
In a preview clip for a future episode, Kim tells her sister Khloe: “I just got the blood test back, and I am pregnant!”
Previous episodes showed the star’s fertility struggles with her husband, rapper Kanye West, and she even confessed that an attempt to get pregnant through IVF had failed.
Ahead of her show being broadcast in the US, Kardashian, 34, tweeted: “Who is excited for tonight’s KUWTK finale?!?!?! There’s some exciting news to share so make sure you tune in!!!!!”
Kardashian later confirmed the good news to Glamour in an interview, saying: “We are so beyond excited.”
Opening up about how motherhood has changed her, she admitted: “It’s been the biggest lesson, and the biggest joy of my life. North has taught me patience. There’s nothing I wouldn’t do for her.”
She went on, adding: “And nothing I wouldn’t do for my husband. She’s empowered us to want to be the best parents and the best spouses.”
The star revealed that her attitude to fame has changed thanks to her role as a mother saying: “Now I enjoy my family time so much, there is this sense of, If it all went away, and I was just a mom, I would love my life.”
Kim’s mom Kris Jenner sent her congratulations to the couple via Twitter and said she can’t wait to meet ‘your new little love bug.’
Kardashian, 34, and her husband Kanye West, 37, welcomed their first daughter, North West, in June 2013.
Since getting married in May 2014, the pair made it no secret of their plans to expand the family.
“I’m hoping so. You know I kind of wish I was pregnant at the same time Kourtney is. She’s like more than half way in, so you know, we’re trying,” Kardashian told reporters back in August, when asked if she sees another baby in the near future.
“It would be fun. There’s a lot of craziness in the house, so why not add pregnancy hormones to the craziness? It would be like a partner in crime. Someone to know those cravings that you’re really going through.”
A month later, Kardashian again spoke of her desire to get pregnant, telling Australia’s “Today” show, “We’re trying. I guess, it’s all in God’s hands.”
Getting pregnant the second time around was no easy task for Kim and Kanye.
“I’ve been having sex 500 times a day,” Kardashian confessed to Khloe on a preview for the reality show’s tenth season. “I was like, ‘I’m ovulating today!’ So I made [Kanye] come to my photo shoot. You know what, I don’t feel bad about that for one second. You gotta get it in where you can get it in.”
