Parenthood will change every one of us, especially stars who just recently entered that phase in their life. They either update us every day about their new bundle of joy, or they keep it to themselves like Jessica Biel and Justin Timberlake.

Jessica, 33, and Justin, 34, have been keeping a low profile since Jessica gave birth to their son, Silas, last April. But Jessica made a public appearance last Friday night at the fundraising telecast for Think It Up, a new educational initiative set up by the Entertainment Industry Foundation (EIF), at Barker Hangar in Santa Monica, Calif. Jessica was pictured with her close friend since 2010, Jennifer Garner at the event.

Jessica and Jennifer are both supporting EIF for its cause to support the nation’s students, teachers and schools. The two are helping to generate excitement about learning everywhere in America and building a sense of optimism about the changes underway in classrooms across the country.

Meanwhile, Justin Timberlake also had his share of showing how amazing it is to be a dad after Jessica shared previously her magical experience as a mother. Justin brought photos of their son, Silas, to his appearance on The Tonight Show with Jimmy Fallon and shared it on social media. “It is the most insanely, amazing, most beautiful, unbelievable thing that could ever happen to you,” Justin said proudly, adding his first son’s word was “da-da.” According to Justin’s friend, Lance Bass, he saw the changes Justin had after Jessica gave birth to Silas.

“It’s been five months and it’s so amazing to see a friend go through this, because you know, I grew up with him since he was 14 years old,” Lance said. “But to see this amazing dad now…all he wants to talk about is the kid.”

Jessica Biel and Justin Timberlake kept their parenthood experience private and shared just two photos of Silas since birth.
