Kim Kardashian and Kanye West are expecting a baby boy, the reality star revealed through an adorable Father's Day message on Sunday.
Kim broke the highly anticipated news on Instagram alongside a photograph of her daughter, North West, sitting on her rapper father's lap as he read to her.
"Precious moments like this when we were traveling on tour with you are what I live for," she wrote, before adding: "You're such a good daddy to North & you will be the best daddy to our new son too!"
The message to fans followed an earlier picture of Kanye kissing his daughter on the cheek. "I'm so lucky to be married to a man who is so in love with his daughter, your bond so irreplaceable," she captioned the snap.
"Thank you for being such a good dad! We love and appreciate you so much! We are so blessed to have you!" Kim and Kanye revealed the happy news that they are expecting their second child earlier this month.
Kim, 34, made the announcement in a teaser for an episode of Keeping Up with the Kardashians. In the clip, Kim is seen being told that she's pregnant during an appointment with her doctor.
She then tells sister Khloe: "I just got the blood test back, and I am pregnant!" Momager Kris Jenner was the first to congratulate her daughter, writing to her on Instagram: "I can't wait to meet your little love bug," and adding the hashtag #youaresobeautifulpregnant.
The "little love bug" will be a brother for Kim and Kanye's daughter North West, who turns two this month. Not long after the baby news came to light, 'South West' began trending on Twitter – a sign that fans are hoping the Kardashian Wests keep up the geographical theme.
It is understood that Little North is set to become a big sister in December.
