ET's Lauren Zima spoke with the 36-year-old actress at American Express' Live Life launch event in New York on Monday, where she opened up about whether she and husband Justin Timberlake actually have plans to expand their family after his January comments that he wants "as many kids as we can."
"Did he say that? Oh, that's interesting," Biel joked, before sharing their hopes to give 3-year-old son Silas a sibling. "You know, kids are amazing. They are really hard, but they are really amazing."
"I think it would be amazing to have a bigger family," she continued. "I don't know if that is in the cards for us, we will see. But I am feeling him. I don't know what that means exactly, but I like his dedication!"
Timberlake is just as dedicated to Biel as he is to his plans for more children. The "Say Something" singer constantly gushes about his wife over social media, and according to Biel, there's no doubt that they have each other's back.
"It's so easy to get out of touch with your partner, especially if you're over here in one part of the world, and they're over there in another part of the world. Very easily you can become strangers," she noted. "So having his back and he having my back in every moment of our lives, even if it's the decision of what's for breakfast, you feel safe and you feel like you're not alone in the world. So it's very important for us."

"[Becoming parents] changed everything, because we're both in awe of each other," Biel revealed. "In many moments, I will do something and feel it's a bit of a mom fail, and kind of look over at him. There's no judgment there, so it's a safe place that we've created for ourselves and our partnership."
The couple is also learning how to navigate parenting a toddler on the road, as Biel said she "pops in and out whenever I can" on Timberlake's Man of the Woods tour. "We spend a lot of time on tour together, which is really fun, but really hard now with a kid," she expressed, noting that Silas often "prefers to wear his pajamas" on the road, before raving over her husband's incredible performances night after night.
"What he can become when he's performing is like otherworldly almost. And the energy that he gives out and the energy he's receiving is magic," she said. "It's very special to watch someone who's close to you do what they are meant to do, what they've been put here on this earth to do. That's what I feel when he's performing. If he didn't have it in his life, he would be, like, dying inside, you know what I'm saying?"
