« I think we were FaceTiming and you said, ‘Hey, you want to know a secret?’ and then Jessica walked in and you put your hand on her stomach. You were like, ‘I’m having another baby!' » she said.

The couple was reportedly able to keep the pregnancy a secret during the pandemic because they spent most of their time in Montana with their firstborn son, Silas, 5. 

Timberlake said Silas is « super excited » about becoming an older brother.
