Cassie has welcomed her second child with husband Alex Fine.

The singer and model shared the bright news on Saturday (March 27) on Instagram, where she posted a series of family photos featuring the newborn.

“On Monday March 22nd, 2021 @ 10:22am our hearts got bigger. Welcome to the world baby girl! We love you so much Sunny Cinco Fine!” she wrote alongside the family portraits.

Fine celebrated Sunny’s birth on Instagram as well, with a letter to his two children. The couple welcomed their first child together, daughter Frankie, on Dec. 6, 2019.

“I woke up this morning with you two and your mama and took a moment to let it sink in that we created the perfect family that isn’t perfect but its filled with so much love,” he wrote.

Fine’s note continued: “I always thought my purpose was to inspire others through wellness and give back to those who are less fortunate but I was wrong. That is my legacy and you two girls are my purpose, I am put on this earth so I can help you shine and have your beautiful lights touch a lot of people. Just holding both of you I know you are destined for absolutely amazing things and I’m put on this earth to support what you two love doing. I’m so happy you two are so close on age like myself and my brothers because you will quickly learn that iron sharpens iron and you two will make each other better. I hope you read this when you go to your prom, graduation, when you’re married with your own families (I have to approve of course), and even when I’m gone (not for 100 more years don’t worry) to understand how much my heart is filled with joy, pride, and love for my 3 girls. I am happy you chose me as your Da.”

The pair had announced that baby No. 2 was on the way in December, a few days after Frankie turned one.
