Kim Kardashian and Kanye West have welcomed another member to their family! The 38-year-old reality TV star announced the birth of their fourth child, a baby boy [1], on Twitter on Friday. "He's here and he's perfect!" As with the birth of their third child, Chicago [2] in 2018, Kim and Kanye used a gestational carrier [3], although they reportedly worked with a different surrogate [4] this time. The exciting news comes just days after Kim and Kanye shared a glamorous evening at the Met Gala [5] in New York City.

He's here and he's perfect!

A name for the baby [8] has yet to be announced, and Kim has actually said she likes to wait a few days until landing on a name she connects with. In a recent interview on Jimmy Kimmel Live, however, Kim said she was considering the name Rob, in honor of her brother and late father.

Kim first confirmed the news [9] that she and Kanye were expecting during an appearance on Watch What Happens Live in January. Their fourth child will be joining 5-year-old North, 3-year-old Saint, and 1-year-old Chicago, who the baby apparently resembles most closely, Kim tweeted.
