Kim Kardashian has revealed her second baby with Kanye West is a boy.

Kim Kardashian, 34, revealed the news on Father’s Day, tweeting on June 21: “You’re such a good daddy to North and you will be the best daddy to our new son too!”

The reality star first let people know she was pregnant on her show Keeping Up with the Kardashians.

Kim Kardashian and Kanye West had their first child, daughter North West, in June 2013.

She is expected to give birth in early December.

Kim Kardashian has previously talked about speculation over the new baby’s name being “ridiculous” but has ruled out naming the boy after another compass direction.

Speaking to National Public Radio in America, Kim Kardashian said South West wasn’t in the running to follow North.

“I don’t like South West… North will always, you know, be better and be more… she has a better direction,” Kim Kardashian said.

It’s been a dramatic few weeks for the show with pregnancy news and Kim Kardashian’s step-mother Caitlyn Jenner going through the transition process from a male to a female.

On her Twitter feed Kim Kardashian spoke about spending Father’s Day with Kanye West and their daughter North.

“Your bond is so irreplaceable! Thank u for being such a good dad! We ❤️ &appreciate u so much! So blessed to have u.”
