Justin Timberlake has opened up for the first time about having another baby with his wife, Jessica Biel.

The musician and actress tied the knot back in 2012.

The couple welcomed their first child, a son named Silas, in April 2015.

Silas now has a baby brother named Phineas.

Justin Timberlake spoke about his newborn son during a virtual appearance on The Ellen Degeneres Show.

Ellen was one of the first people outside his and Jessica's immediate family to learn that they were expecting.

"His name is Phineas," the 'Can't Stop the Feeling' singer said.

"And he's awesome, and he's so cute, and nobody's sleeping. But we're thrilled.

"We're thrilled and couldn't be happier, very grateful."

Justin Timberlake was also asked about how parenting two kids compares to one child.

He joked: "We don't see each other anymore. It's a lot of fun.

"I guess the saying goes go from a zone defense to a man-to-man really quickly.

"It's great. Silas is super excited."

As for how is Silas feeling, getting used to being a big brother, Timberlake said: "Right now he's very much liking it.

"Phin can't walk yet or chase him down, so we'll see what happens."

Justin Timberlake soon stars in 'Palmer', which hits Apple TV+ later this month on January 29th.
