Jessica Biel Opens Up About Her Adorable Baby Son, Silas

Jessica Biel sure is smitten with the new man in her life. The actress gave birth to son Silas Timberlake back in April, and this morning on the Today show, she opened up about being a new mom while promoting her hilarious Funny or Die PSAs. (The videos, which star Biel, Whitney Cummings, and Joy Bryant, are a part of a campaign with WomanCare Global to educate women about reproductive issues.)

"He's wonderful," she told co-anchor Willie​ Geist of her baby boy. "He's just a joy. It's an amazing, amazing experience." While Biel may be loving every second, she now understands the difficulties of parenthood. "[It's] incredibly hard, the hardest job in the world and I've never been more thankful and grateful to my own mother," she said. "Oh my gosh, I'm going to call her right after this actually and just thank her. What you have to do for your kid—it's an amazing responsibility and the biggest joy ever."

Thankfully, Biel's husband Justin Timberlake is right in the thick of it with her for duties ranging from changing diapers to getting up for midnight feedings. "He is doin' it all," she said with a smile. "He is in there, deep."
