Kim spoke up on Friday morning, calling the baby "gorgeous" and confirming she was in the delivery room when Khloe gave birth.
💕 @khloekardashian I'm so happy for you! Your baby girl is so beautiful! You are so strong, you made that look so easy! I can't wait for our baby girls to grow up as best friends the way we are! I'm so happy I was able to return the favor of holding your leg while you pushed LOL
Kylie Jenner, who stayed in California with her daughter Stormi, posted her response on Snapchat. Alongside a shot of a road near her home, she wrote, "Kongrats, Khloé! It"s a Girl!" with pink and white balloons.
It's worth noting that none of them mentioned Tristan in their messages. Kourtney, Kendall Jenner and Rob Kardashian have remained silent so far, but we'll update this post if they decide to chime in.
