"I guess the biggest thing is we hope the baby stays inside and can get as big as possible before this big event they have to go through," Christina continued. "It's just a couple more weeks, so I'm gonna try to take it easy and hope for the best."

Christina and husband Paul Costabile, who are also parents to 2-year-old daughter Carmella, announced their pregnancy in July. Six months prior, the artist suffered a miscarriage at 11 weeks.

Christina said she went public with the heartbreaking news to "help change the story [and] stigma around miscarriage, secrecy and shame," adding, "I am ever reminded how amazing and powerful women are at making life and at healing. To all the mothers who have been here and who will be here, I see you and I love you."

And just weeks before the loss of her daughter, Christina opened up about honoring her pregnancy experience after such a tough journey to motherhood. 

As she described on Instagram, "i never wanted to do a maternity shoot. i didn't take any photos when i was pregnant with carmella because i was so traumatized by the experience of expanding so much, but then after having a miscarriage in january, everything changed for me. i truly am grateful to be pregnant and grateful to be a woman. i am so blown away by what our bodies can do. i don't know if i'll ever be pregnant again, so this time i'm going to celebrate and honor my pregnancy, my baby & my beautiful body."
