Demi LovatoHis newborn granddaughter Xiomara died following an emergency C-section, says the singer’s younger sister, Madison De La Garza. De La Garza posted a statement on Instagram on Saturday (October 26), and Lovato shared her sister’s heartbreaking message.

“On the evening of September 27th, after an emergency c-section, Ryan and I held our baby girl for the first and last time. Thank you, Xiomara, for making us the parents of the most perfect angel in heaven. Mommy and Daddy love you sweet girl,” De La Garza, 22, she wrote in her post. She and friend Ryan Mitchell had it announced the pregnancy on Sept. 7, as well as De La Garza’s October due date.

“I love you so much, Xiomara. An angel in every sense of the word. I’ll be your aunt forever,” Lovato commented on her sister’s post on Saturday.

Dallas Lovato, their older sister, wrote an emotional poem: “Baby girl Xiomara, I miss you everyday. I’ll take care of your mother so you can fly. Watch over us and guide us and give us little signs. One day we will come to see you, it may take some time. Not a day will go by without you in our hearts. I wish we had more time together before you left. So have fun in your new world, the one we don’t see. ‘Cause every breath I take, I’ll take one for z.”

Dianna De La Garza, mother of the brothers and grandmother of baby Xiomara, wrote: “They say that when you meet your grandson for the first time, you feel a love that cannot be explained in words. I felt that love and I will until the day I die. I love you my sweet niece Xiomara. Thank you for making me a real ‘Grandma D.'”

On Saturday, Lovato also shared her younger sister’s post in a Instagram story on her own, where she wrote: “RIP to my beautiful and perfect niece Xiomara. I’m so thankful I got to hold you. I will forever be your aunt.”

“I love you so much @maddelagarza,” she said.
