The responses to her simple tweet are being met mostly with questions about the baby’s name, which has yet to be revealed.
Kourtney, the eldest Kardashian sister, revealed that Kim’s surrogate was in labor after surprising her mother, Kris Jenner, on The Ellen Show yesterday.
Kardashian’s new baby is Jenner’s 10th grandchild.
In January, it was reported that Kardashian and husband Kanye West were expecting a fourth child via surrogate, one year after welcoming their daughter Chicago (also via surrogate) one year prior. That same month, Kardashian confirmed that their newest addition was due “sometime soon” on an episode of Watch What Happens Live with Andy Cohen.
