In April 2021, Jessica Biel sat down for her own interview on "The Ellen DeGeneres Show" and opened up about what life with two kids was like with Justin Timberlake. Biel said their children were getting along well and that oldest son Silas has remained in the spotlight. As she put it, "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."

Biel added that both of her sons were funny and had a good sense of humor. "Everything Silas does is hilarious and anything Phin does is hilarious, so they just laugh at each other all day long," she said.

Biel offered details about the sleep training she and Timberlake were working on with Phineas, but it sounded like it was hard on both of them. She admitted that the whole family was pretty tired with the new baby, but added that, "I think that's why they're so cute is because you just look at them and you're like, 'I'm so tired, but you're so cute.'"
