Kim Kardashian and Kanye West are expecting their second child and everyone has been curious to know the gender of the baby.

Well, late on Sunday, Kim Kardashian closed out Father's Day by revealing the gender in a sweet Instagram and Twitter message to Kanye West.

The "Keeping Up With The Kardashians" star announced it's a boy. She broke the news in an emotional message praising Kanye for being a doting father to their daughter North and that she knows he will be equally attached to the new one also. 

On Sunday, Kim shared a photo of the rapper on Instagram and wrote: "Precious moments like this when we were traveling on tour with you are what I live for. You're such a good daddy to North & you will be the best daddy to our new son too!"

She posted a similar message on Twitter.

With this, Kim has confirmed rumours that the couple was expecting a son. After struggling to conceive, Kim announced the pregnancy in May and ever since then, has been surrounded by stories about fake pregnancy, surrogacy and bearing twins.

But now, all those speculations have been laid to rest. The little one is expected to arrive in December and Kim Kardashian and Kanye West have confirmed that he won't be named "South".
