Biel and Timberlake welcomed their second child, a son named Phineas, in the summer of 2020, though his exact birth date is still unknown. Despite news of Phineas's birth circulating that autumn, it wasn't until January 2021 that we found out more about their newest addition, as Timberlake first talked about his youngest son while on "The Ellen DeGeneres Show."
"He's awesome and so cute," the singer shared at the time, per People. "Nobody's sleeping, but we're thrilled. We're thrilled and couldn't be happier. Very grateful."
Of him and Biel going from one kid to two, Timberlake joked: "We don't see each other anymore and . . . no, it's a lot of fun. But I guess the saying goes, 'Go from a zone defence to a man-to-man really quickly.' You sort of, like, split, 'You go get that one, I'll get this one!'"
A few months later in June, Biel appeared on Dax Shepard's "Armchair Expert" podcast, where she revealed that she'd had her youngest son in secret, though not on purpose. "It wasn't like it was supposed to be a secret," she said. "It was, just, COVID happened, and then I went to Montana with my family and never left."
It's unclear whether Phineas has a middle name like his older brother, but we do know he has a sweet nickname: Phin!
