Rob Kardashian is already smitten with his new little bundle of joy.
“Rob was so emotional. He started crying when he saw his daughter,” a source tells PEOPLE. “He’s been waiting for this moment for such a long time! She already has him wrapped around her finger.”
Kardashian, 29, was in the delivery room when his bride-to-be gave birth to the newborn via cesarean section. Chyna, 28, arrived at Cedars-Sinai Medical Center in Los Angeles early Thursday morning and welcomed their baby girl at 9:18 a.m., weighing 7 lbs., 5 oz., according to E! News.
Hours after meeting his adorable daughter, Kardashian took to Instagram to share a photo of the newborn. “Today was amazing🙂 I am so lucky!! Thank you @blacchyna for having our baby and being so strong ! I love you so much and can’t wait to see her get older day by day with you Chy! I love you and Dream so much and Appreciate both of you. I know everyone saying that’s my twin but that’s def your nose Chy lol,” he penned in the heartfelt post.
