They are two of the more successful parents around – however, Jessica Biel and Justin Timberlake's son has a very relaxed response to his father's famous work.
In an interview, the actress, 39, has shared how their six-year-old, Silas, now recognises his musical hits.
However, speaking on US TV's The Tonight Show, she told host Jimmy Fallon: "Whenever he hears daddy's song he'll go, 'Oh yeah, that's Dad, no big deal, whatever.'"
Similarly, Silas can identify the Cry Me A River and SexyBack singer's Trolls character Branch.
But, despite lending her voice to children's series Pete The Cat, Biel's eldest child appears disinterested in what his mother gets up to for work.
The star joked: "I tried to get him to watch the show; he will not watch."
As well as her Golden Globe and Emmy-nominated turn in series The Sinner, she has appeared in the more adult-appropriate remakes Total Recall and The Texas Chainsaw Massacre.
With 40-year-old Timberlake, who she married in 2012, she also has a 10-month-old son called Phineas.
It comes after Biel recently appeared on The Ellen DeGeneres Show, when she revealed Silas and Phineas have an adorable brotherly relationship.
The actress said: "Both think the other one is hilarious. Silas, he is the performer, he wants to make the jokes and he wants the whole attention on him, so Phin only has eyes for him."
Discussing the extra workload that comes with being a mother-of-two, she added: "A very wise friend of mine said, 'One is a lot, and two is a thousand.' And I said 'Oh my god, you're right.'
"That's exactly how it feels. You're just man-on-man defence, one person's over here and the other person's over here."
