Silas Randall Timberlake
Silas is Justin Timberlake and Jessica Biel’s first child. He was born in April 2015, and the couple confirmed his full name, Silas Randall Timberlake, after his birth.
Over the years, Timberlake and Biel have occasionally offered small glimpses of family life without creating a comprehensive public profile of their son. Biel has spoken about Silas in interviews connected to her work as an author and parent, describing him and his younger brother as curious and compassionate.
#1 Best Overall
Silas’s reported interest in music
In 2025, Biel said that Silas had developed an interest in music and was an aspiring DJ. She also described him using music by his father at a birthday party. That is a parent-reported description of a current interest—not evidence that Silas has begun a professional career in entertainment or plans to follow his father into the music business.
Timberlake is known for his work as a singer, songwriter, performer, and actor, but the available reporting does not establish that Silas is pursuing a public career. Respecting that distinction is especially important because his parents have been selective about what they reveal about him.
Phineas, the younger son
Phineas is Justin and Jessica’s second child and younger son. The family kept the pregnancy and birth relatively private. Timberlake confirmed the baby’s name and sex during a January 18, 2021 appearance on The Ellen DeGeneres Show, telling host Ellen DeGeneres that the baby was a boy named Phineas.
Timberlake described the infant as “awesome” and “so cute” and joked about the sleep disruption that comes with having a newborn. The appearance confirmed Phineas’s name, but it did not establish a verified exact birth date. Reliable reporting places his birth in 2020, so it is more accurate to use the year than to assign him a specific birthday.

However, the public record remains limited by design. There is no reliable basis for filling in private details about his schooling, personality beyond comments directly attributed to his parents, or everyday life.
What have Jessica Biel and Justin Timberlake said about the brothers?
Biel has discussed the boys together in a lighthearted way, including the reality that siblings are not necessarily best friends every day. Her comments portray a familiar sibling relationship rather than a carefully managed celebrity-family image: the brothers have different personalities, sometimes get along, and sometimes do not.
In 2024, Biel referred to Silas as 9 and Phineas as 3 while discussing her children’s book and family conversations. She described the boys as curious and compassionate and said the book was dedicated to them. She has also talked about explaining menstruation and body-related topics to her sons in an age-appropriate way, framing those conversations as part of teaching empathy and helping children understand their bodies—not as an invitation to disclose their private lives.
The brothers have also accompanied their parents in selected family and professional settings. That has included travel connected with Timberlake’s touring schedule and a rare public appearance with both boys in November 2024. Such appearances show that the children sometimes participate in family events, but they do not suggest that Timberlake and Biel have abandoned their generally cautious approach to publicity.

The clearest description is selective disclosure. Timberlake and Biel have confirmed their sons’ names and occasionally shared family anecdotes or limited images, while withholding the kind of detailed information that would amount to a public biography.
Public coverage has noted that images of the boys have often been limited or presented in ways that reduce facial identification. It is safer to describe this as an observable pattern than to claim that the family follows a formal privacy policy unless either parent explicitly uses that term.
The approach also explains why many online claims about the children should be treated cautiously. Fan accounts, anonymous gossip, social-media speculation, and captions written by paparazzi outlets are not equivalent to a statement from Timberlake or Biel or to reporting from a reputable source. Unsupported claims about schools, locations, health, security, friends, religious upbringing, political views, or private family disputes do not belong in a responsible account of the family.
Jessica Biel’s children’s book and the family connection
Biel’s 2024 children’s book, A Kids Book About Periods, is a related parenting and education project rather than a book about Silas and Phineas. She dedicated it to her two sons and has explained that conversations within her own family helped shape her interest in making menstruation easier to discuss.

The book is intended to support open, age-appropriate conversations about bodies and menstruation. The publisher describes it as a 64-page hardcover aimed approximately at ages 7 to 9 and credits Biel as the author. Its connection to the Timberlake-Biel family is therefore contextual: Biel has discussed the book alongside her experiences talking with her sons, but the children are not subjects, spokespeople, or endorsers of the product.
For families interested in the educational angle, A Kids Book About Periods by Jessica Biel may be a relevant resource to investigate. Parents should decide whether any body-literacy book is appropriate for their child’s age, questions, and level of understanding.
