Mowry continued, "Thank you for being patient with me learning how to braid your hair, and I will never forget our duet singing the national anthem at Napa's soccer game. I love you. I love you. I love you. You are gonna make one gorgeous angel. My heart and prayers are with every victim of this tragedy."

In a separate Instagram post, Housley wrote, "My sweet, sweet...Alaina. Oh how I miss you. Oh how I miss u. #heartbroken."
