OMG! Kim Kardashian revealed that her fourth child with Kanye West looks just like her 16-month-old daughter, Chicago. Their new baby boy was born on Thursday, May 9, via surrogate and the parents already can’t stop gushing.

“He’s also Chicago’s twin lol I’m sure he will change a lot but now he looks just like her,” the 38-year-old divulged on Twitter moments after announcing his arrival.

Kim announced this exciting detail about her new bundle of joy moments after making an official birth announcement. “He’s here and he’s perfect,” the Keeping Up With the Kardashians star wrote on Twitter about her precious baby boy.

Fans are so excited about arrival and quickly congratulated the newly minted family of six. Of course, no one has any doubts that their new baby will be just as adorable as their other children. “The more babies you have the [cuter] they are,” one person responded. Someone else raved, “Congratulations we already know he’s gorgeous because you and Kanye make pretty babies.”

People already think Chi looks a whole lot like her famous mama so it looks like their fourth baby will also take on some of her trademark looks. “So basically he looks like YOU!” a follower noted while someone else added, “Soooo … he’s your twin lol.”

Next important detail that will be revealed will most likely be the little man’s moniker. As of April, the parents didn’t really have a lot of name options. “I actually do not,” Kim confessed to Jimmy Kimmel after being asked if they had any top contenders. “Actually, I do have one name … I was truthfully thinking of just naming him ‘Rob,.’ [Like] my brother, Rob.” The Selfish author’s late father, who passed away in 2003 from esophageal cancer, is also named Robert Kardashian.

However, there was one thing holding her back. She continued, “But then, it’s kind of like North, Saint, Chicago, Rob … it doesn’t really go … But, I really was feeling that, or like Robert, and my brother approved it. So that’s like our one kind of name.”

We can’t wait for more baby details!
