Kim Kardashian jokes that North West leaked news of fourth baby

Season 16 of Keeping Up with the Kardashians premiered on E! Sunday night, and we learned that Kim Kardashian thinks her daughter, North West, leaked the news that Kim and Kanye West are expecting another baby. “Do you know who I think our informant is,” Kim told Kylie Jenner. “North.”

Jenner was shocked that it was North who leaked the news, but Kardashian explained that North told everyone at school: “A mom at school texts me and goes, ‘Congrats, I heard you’re having a baby brother,’ and I go, ‘What?’ And I go, ‘Oh, that,'” Kardashian explained. “And she goes, ‘Yeah, North is going around saying she finally has a baby brother so Saint won’t bother her anymore.'”

Excited fans have been tweeting the couple their congratulations since the episode aired.

While fans are excited about the newest Kardashian West, Kim wasn’t quite ready to break the news to the public. After revealing the news to her family, she swore them all to secrecy: “But you guys, it’s really top-secret. We don’t want anyone to know until it happens,” Kim stated.

Kim eventually revealed she and Kanye are expecting their fourth child when she was on Watch What Happens Live With Andy Cohen in January, but had to do some damage control after North let the secret slip. After Jenner asked her what she was going to do, Kim told her that she “killed the rumor.”

Now that Kim knows who the leaker was, it’s likely she’ll be keeping her secrets from North from now on.

Keeping Up with the Kardashians airs weeknights at 10 p.m. on E!.
