'Keeping Up With The Kardashians' star Kim Kardashian treated her followers last Father's day as she revealed the sex of her second baby with Kanye West in her Father's day tribute post on Instagram.

While on tour, West at times brings along his wife, Kardashian and their two-year-old daughter North West with him and just right on time, last Father's day, Kardashian posted a sweet photo of her daughter and her husband having a little bonding time while reading a book.

The father-daughter duo looked very well bonded as they were very focused on reading the book while North sat on top of her dad at a hotel with Kardashian capturing the sweet moment as she wrote alongside the picture on Instagram, "Precious moments like this when we were traveling on tour with you are what I live for." Kardashian said.

But the surprise was the second part of her caption. "You're such a good daddy to North & you will be the best daddy to our new son too!" Kardashian added finally revealing that they will have a baby boy!

Indeed it is a perfect combination. The two get to experience being parents to both a girl and a boy and Kardashian's due date happens to be this December which only means that they will definitely have the sweetest Christmas together especially for their new baby boy.

The reality star for sure, as many may have guessed to be really excited especially since she had a hard time trying to get pregnant the second time around as evidenced in the latest KUWTK series.

"We are so beyond excited," Kardashian recently told Glamour magazine of her second pregnancy. "I'm a completely different person...If it all went away, and I was just a mom, I would love my life," she added. So as they wait for the final arrival of their soon-to-be baby boy, congratulations to the expectant second-time parents!
