Justin Timberlake turned a major charity runway into a family affair when his rarely seen sons, Silas and Phineas, joined him for a surprise appearance in Denver. The heartwarming moment came as the singer and his children supported his niece Zaya, as reported by Page Six.

The singer, 45, attended the Global Down Syndrome Foundation’s annual Be Beautiful Be Yourself fashion show on Saturday. The event celebrated Zaya, aged 7, who has Down syndrome and took a starring role in the festivities.

Before walking the runway, Timberlake carried Zaya while posing for red carpet photographs with her parents, Rose and Justin Biel. Justin Biel is the younger brother of Timberlake’s wife, Jessica Biel.

Timberlake later stepped onto the runway with Zaya, Silas and Phineas. The appearance gave his sons, aged 11 and 6, an unexpected opportunity to participate in the annual fashion show alongside their famous father and cousin.

A video posted on social media showed Timberlake dancing while holding Zaya in his arms. Silas also displayed some dance moves as the family made its way through the event.

Phineas appeared to be the more reserved of the two brothers during the runway appearance. The 6 year old remained close to Timberlake’s side while the crowd watched the family together.

Still, Zaya was unmistakably the center of attention. She waved and blew kisses while audience members cheered, embracing the excitement as Timberlake and her cousins accompanied her on the runway.

Timberlake offered another look at the celebration in an Instagram Story posted Sunday. In the image, he held the hands of Phineas and Zaya, while Silas helped hold up Zaya’s other arm.

Phineas coordinated with his father by wearing a black suit. Silas chose a different look for the occasion, appearing in a leather jacket, black pants and sunglasses.

Timberlake captioned the photograph by saying that they had walked his beautiful niece down the Global Down Syndrome runway the previous night. He added a red heart emoji to the message.

The singer also shared a picture of himself and Zaya smiling together on the red carpet. He celebrated the family moment with the brief caption, “proud uncle!”

Jessica Biel, 44, was not able to attend this year because of work commitments, according to a press release from the Global Down Syndrome Foundation. Her absence did not leave the Biel family without support from one of her close friends.

Beverley Mitchell, Biel’s fellow “7th Heaven” star, attended the event in support of the family. Mitchell’s presence added another familiar face to the evening as Zaya took her turn in the spotlight.

The event also delivered a major fundraising result for the organization. It raised a record $2.7 million to support research, medical care and advocacy for people with Down syndrome.

Timberlake and Biel’s family has supported the annual gathering for years. Jessica joined Zaya on the runway at the previous Be Beautiful Be Yourself fashion show in October 2025.

Jessica also walked in the nonprofit’s annual fashion show with Silas and Phineas in November 2024. That appearance came during the event at which Zaya was named as the foundation’s ambassador.

The Denver celebration continued that family tradition with Timberlake and his sons taking part this time. Timberlake and Jessica, who have been married since October 2012, have repeatedly brought their family together to support Zaya and the foundation’s annual event.
