Jessica, 33, who welcomed son Silas in April with husband Justin Timberlake, admitted that being a parent is "incredibly hard," but she's loving every minute of it.

"[It's] 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."

Jessica said that her 6-month-old son is "wonderful." "He's just a joy," she said. "It's an amazing, amazing experience."

The former 7th Heaven star also revealed that her multitalented hubby, 34, is also a great parent, getting up in the middle of the night and handling diaper changes. "He's doing it all," she said. "He is in there, deep."

Justin joked with his pal Jimmy Fallon earlier this month that he and Silas like to watch the PGA championship together, and he's succeeded in making sure that his little guy's first word was "Dada." "It is the most insanely amazing, most beautiful, unbelievable thing that can ever happen to you," he said of being a dad.

Jessica appeared on Today to promote her new Funny or Die videos, which she made in conjunction with Woman Care Global to educate women on reproductive issues. She also spoke at the Clinton Global Initiative earlier this week about the importance of women of all ages learning more about their bodies. She admitted her own lack of knowledge when she was thinking about starting a family and began looking for information about going off birth control. "I had no idea," she admitted. "I felt so embarrassed … I knew nothing."
