Jessica Biel Celebrates World Down Syndrome Day with Adorable Niece

LOS ANGELES, March 21, 2025 — Jessica Biel is celebrating World Down Syndrome Day by sharing heartfelt moments with her niece, Zaya. The actress, 43, took to her Instagram on Friday to post a series of charming photos featuring her and Zaya, the daughter of her brother Justin and his wife Rose.

In the photos, Biel sported an elegant all-black dress adorned with feathers, while Zaya looked adorable in a white tulle dress decorated with a pink ribbon. One image captured the pair blowing kisses to the camera, while another showed them holding hands and beaming with joy.

“Today is #WorldDownSyndromeDay, a cause close to my heart because of my wonderful niece, @lovelyzayab,” Biel captioned the post. “Along with @jpbiel and @shamanrose, I’m supporting @globaldownsyndrome to help more individuals thrive. Everyone deserves the care they need. Let’s make a difference together! Link in bio to donate 💙🌎.”

Biel has long been an advocate for individuals with Down syndrome. In November 2024, she and her family joined Zaya at the Be Beautiful Be Yourself fashion show in Denver, where Zaya was honored as a Global Ambassador for the Down Syndrome Organization. Photos from the event displayed Biel and her sons walking down the runway with Zaya leading the way.

Reflecting on the impactful evening, Biel wrote, “Walking the runway with my amazing niece was an unforgettable honor. Huge thanks to the @globaldownsyndromefoundation for creating such a profound, empowering event and for all the incredible work you do. My heart is so full. ♥️”

Biel, who shares two sons — Silas, 9, and Phineas, 4 — with musician Justin Timberlake, previously participated in a Q&A promoting her debut children’s book. During the session, she expressed her joy in raising her sons. “The best thing about being a boy mom is playing; I think playing with my sons is the most fun,” she told a young admirer.

The actress’ post gained warm reactions, including comments from Timberlake and followers expressing gratitude for her advocacy and celebrating Zaya’s uniqueness. Other public figures observing World Down Syndrome Day also shared their tributes.
