"And that just felt like such a divine purpose and something that when I started thinking about it, felt like such joy." Willis said she recalls recently talking to Thomas about becoming a parent, noting that she "can't wait" for the special moments she and her baby can share together. "I was talking to my partner the other day and saying, 'You know, when I go to the farmers market, I call it church because I leave and I feel so excited,' " she said. "And the idea of being able to bring my kids in like a little cart or something brings me so much delight, I can't even ... I can't wait."
