Ciara and husband Russell Wilson are sharing exclusive pictures of their new baby, Sienna Princess Wilson, on Russell's new app TraceMe.

"I'm so excited to be opening up my world to you on TraceMe," Ciara said, "You guys know that I tend to be private with a lot of things, but with TraceMe I can have a genuine, unfiltered connection with you all. My motivation for this was to give back for all of your support throughout the years. We now have a special place where you can get to know more about me, and see all the fun things that go on with my music, my family, my fashion, and so much more."

And the proud mom of two explained that you can check out photos of Mommy and "Baby Sisi" shot by Russell on the app.

But our favorite thing has to be her open letter to Sienna.

"My Princess, it has been the sweetest joy having you in my life. Since the day you were born, watching you grow up has been the greatest blessing a mom could ask for," she begins.

And in a word we could all benefit from, she continues:

"I pray that you will have the Boldness of Rosa Parks. The Intelligence of Maya Angelou. The Compassion of Princess Diana. The Creativity of J.K. Rowling. The Grace & Confidence of Michelle Obama. The Resilience of Serena Williams. An oh…not to mention… The Dance Moves like your Momma! Haha"

Congrats to Ciara and Russell Wilson on their new addition!
