"The hospital restrictions had just changed. And there was a moment there that there was nobody allowed at all and I was really getting nervous about that situation," she recalled.

As a mom of two, Biel told Shepard that the "balance of everything is very different and super hard." "Someone said to me, 'Two is like having a thousand.'

"It's so interesting. It's so funny. The conversations I'm having now with my 6-year-old is so cool," she continued. "Like, he's a real person saying the funniest stuff and he's so sensitive and tender. It's just so interesting to see that part of it happen and the little one is just cute as hell." Biel also spoke about whether or not she wants her sons to follow in their parents' footsteps. "My knee-jerk reaction is 'Oh God, no. Please no," she admitted. "But then I look at these kids and I'm like, 'Oh s—, they're probably going to be musical. What are we going to do? Like, not let them play the piano or not let them take a voice lesson if that's their passion?'... I don't want to be that parent to stifle a dream." Biel added: "But man, if my kid would just be like, 'Let's go learn about corn in Iowa.' [I'd be like], 'Great.' I would so much rather them be an engineer or something."
