Union also took to Instagram earlier today with a sweet post honoring the teen's birthday.
"You are such an inspiration and motivation to get my butt up everyday and fight," she captioned the photo of the two. "When I'm weary, frustrated, full of rage, I see your face and your joy and you living your best life and I want that for all of us."
Zaya's dad similarly made a touching birthday post on Instagram, writing, "Waking up and watching you smile, watching you walk in your truth and live your life your way is one of the greatest gifts I've been able to experience in my life."
"In a world where the color of your skin is deemed a threat you continue to be the bravest person I know and I'm gonna stand by your side until there isn't anymore standing left to do," he continued. "I love you more than words can articulate. I hope you feel all of my love today and everyday of your life."
We also saw Zaya's step-mom and father right by her side (and looking extremely stylish) at her first red carpet appearance earlier this year when she walked the step-and-repeat at the sixth annual Truth Awards, an event that highlights the black LGBTQ+ community.
In honor of the teen's birthday, we're looking back at her cutest family moments.
Take a look below!
Once again, happy birthday, Zaya!
