Jessica Biel is opening up about having baby No. 2.
The actress, who already shares 6-year-old son Silas with Justin Timberlake, welcomed her second child, Phineas, in July.
However, news of a second child took many by surprise, which the "7th Heaven" alum said was not her intention.
"I had, like, a secret COVID baby. It wasn't like it was supposed to be a secret. It was just COVID happened, and then I went to Montana with my family and never left," Biel explained while on Dax Shepard's Armchair Expert podcast.
