"It was one of the most precious moments of my life," the momager gushed.
Jenner wasn't the only member of the famous family to offer her congratulations. Rob's sister Khloé took to Twitter to express her excitement over the little one.
"My new niece is absolutely stunning!!!" she wrote. "So thankful I was able to land in time to witness this miracle happen! Praise God!" The Strong Looks Better Naked author had been in Cleveland, where she was spending time with boyfriend Tristan Thompson.
