"Everyone, meet baby Bella," Heart Evangelista said as she posted on Instagram a photo of her niece last February 17.

"Every time I get to hold my niece in my arms is such a beautiful moment. I can't even describe the feeling - the sense of excitement, gratitude, and just pure magic - that it gives me. It's the most special of life's experiences that I will cherish forever. ⁣⁣" Heart wrote in the post.

Everyone, meet baby Bella. 👶 ⁣⁣ ⁣⁣ Every time I get to hold my niece in my arms is such a beautiful moment. 🌷 I can't even describe the feeling - the sense of excitement, gratitude, and just pure magic - that it gives me. It's the most special of life's experiences that I will cherish forever. 💗⁣⁣ ⁣⁣ As a lot of you might know, I lost my twin babies through a miscarriage last year. My sister and I actually got pregnant at around the same time, so my babies would have had the same birthday as Bella. But instead of feeling any heartache for myself, when I look at Bella, I feel an overwhelming sense of joy. I am so blessed to have her. 💗⁣⁣ ⁣⁣ Bella, I love you so much. You've been on this earth for just a few weeks and already, you've brought so much joy into our lives. Your Mama Heart will always be right here for you, taking care of you, and giving you all the love you deserve and more. Welcome to the world, my dearest Bella. 💗🌷

Along with words of inspiration, Heart also opened up about the miscarriage she had last year, twins who would have been the same age as Bella.

"As a lot of you might know, I lost my twin babies through a miscarriage last year. My sister and I actually got pregnant at around the same time, so my babies would have had the same birthday as Bella.

"But instead of feeling any heartache for myself, when I look at Bella, I feel an overwhelming sense of joy. I am so blessed to have her," Heart added with the photo of herself smiling while carrying Bella.

The actress and model ended her post with a touching message for Bella. "Bella, I love you so much. You've been on this earth for just a few weeks and already, you've brought so much joy into our lives. Your Mama Heart will always be right here for you, taking care of you, and giving you all the love you deserve and more. Welcome to the world, my dearest Bella," she said.

Heart announced her miscarriage in an Instagram post on June 6, 2018, a few weeks after learning she was pregnant.

There are not enough words to express how heavy my heart feels but I know it’s important to share this because it’s part of my motherhood journey. At this week’s Doctor appointment, just as we hit the 3 month mark, we found out that her heart stopped beating. For some it might be early on but for us, we were so ready to meet you, little one. Carrying you made me feel like a completely new person. Just the thought of you taught me what unconditional love feels like. The Doctor told me that there really wasn’t anything we could’ve done, that this happens to a higher percentage of first time moms. I know this is true because so many of you have been open with sharing your experiences. Your kindness and positivity in sharing about your own miscarriages remind me to be strong. I am so grateful for all your love throughout this entire journey. It’s not the end, just another chapter. I take comfort knowing that you’re up there with your twin. I don’t question God about this sad time, I trust in His timing and plan. I hope you all understand that I’ll be taking some time off but your support and kind words will be felt, even if I’m not able to reply. I’m not looking for answers, just peace. For what it’s worth, I already had a name for you. My Mira, funnily enough, I already loved your smile. I know you’ll find your way back to me.
