Friday, Kardashian announced "he's here and he's perfect," adding that their newborn currently looks "just like" Chicago West.
Prior to the official tweeted announcement, TMZ came through to tell everyone that the couple's surrogate was in labor. Additionally, the report noted that an Ellen taping Thursday was originally meant to include Kardashian, though she was reportedly forced to skip it due to the then-impending birth.
The family previously welcomed children Saint and Chicago to the world, as well as their firstborn North West back in 2013. News of their latest first arrived back in January during a Kardashian appearance on Watch What Happens Live.
In a recent Vogue cover chat, Kardashian spoke on her growing involvement with criminal justice reform efforts, including the 90 Days of Freedom campaign.
"It's never one person who gets things done; it's always a collective of people, and I've always known my role, but I just felt like I wanted to be able to fight for people who have paid their dues to society," she said.
In a public Facebook note earlier this week, attorney Brittany K. Barnett provided the backstory on how Kardashian got involved with a campaign she and MiAngel Cody both left well-paid jobs to pursue.
"In 90 days TWO black women lawyers freed SEVENTEEN people from LIFE W/O PAROLE sentences—the second most severe penalty permitted by law in America," Barnett, who said she and the team's clients were "deeply grateful" for Kardashian's boost, said Tuesday.
