"Tristan, thank you for loving me the way that you do!" Kardashian continued. "Thank you for treating me like a Queen! Thank you for making me feel beautiful at all stages! Tristan, most of all, Thank you for making me a MOMMY!!! You have made this experience even more magical than I could have envisioned! I will never forget how wonderful you've been to me during this time! Thank you for making me so happy my love!"
Kardashian didn't share the baby's gender or her due date, but she thanked fans for their "positive vibes."
"Thank you to everyone for the love and positive vibes! I know we've been keeping this quiet but we wanted to enjoy this between our family and close friends as long as we could privately. To enjoy our first precious moments just us. Thank you all for understanding. I am so thankful, excited, nervous, eager, overjoyed and scared all in one! But it's the best bundle of feelings I've ever felt in my life!"
