America’s own Royal Family welcomed its newest member today, Kim Kardashian West announced on Twitter that she and husband Kanye West officially had their fourth child via a surrogate.

This is the second time that Kim has used a surrogate, as birthing complications during the births of North, 5, and Saint, 3, caused the couple to choose surrogacy for the birth of Chicago, 1. Kim previously said that while Chicago was too young to really get what was going, North and Saint were looking forward to their new brother’s arrival

“They are excited,” Kim said. “I mean, I don’t know if they don’t feel it as much because they don’t see my big belly and probably hear me complaining every two seconds. But, we do talk about it a lot, so I think they are really excited.”

“I think my son, I don’t know how he is going to react because he doesn’t get it yet, but my daughter is really excited.”

While Kim did not share the name of the newest member of the Kardashian West clan, she did give fans a hint about the baby’s looks, noting that he was “Chicago’s twin” in a follow-up tweet.
