Jessica, 26, was without boyfriend Justin Timberlake but with her family. The former 7th Heaven actress’ dad, Jon Biel, is a co-founder of the network which brings together donors and non-profit organizations. Kevin James co-hosted the event.

“It’s so nice to be able to work with your family. For me it’s wonderful and something we can do together that makes us feel really good. It’s part of our lives, and we hope that everyone’s inspired to make some type of giving back or volunteering part of their life!”, added Jessica.
