“They are absolutely thrilled,” a source revealed to PEOPLE in September of the couple. “This isn’t something they were in a rush to announce to the whole world, and it’s only been in just the past week or so that they’ve felt comfortable telling most of their inner circle.”

“This is something Khloé has wanted for years and years and yet it’s more than that: She didn’t want it unless she was in the right relationship for it,” the insider said, adding, “This is such a wonderful moment for her: not only is she going to be a mother, she is going to be raising a child with a man she truly loves. Everyone is over the moon for them both.”
