Jon Bon Jovi and dad-times-two-to-be Matthew McConaughey put their best foot forward on behalf of the Entertainment Industry Foundation at the National Conference for Service and Volunteering -- and ET was there!

Shining the spotlight on the power of service in front of an audience of more than 4,500 service leaders, Jon and Matthew shared plans for EIF's new multi-year campaign to help make service and volunteerism a national priority. Michelle Obama and Arnold Schwarzenegger were also among the luminaries at the event.

Matthew McConaughey introduced a brief video with a sneak peek at what EIF and the entertainment industry have planned, while Jon performed a musical set to celebrate the year-round work of hundreds of service organizations represented at the event.

Jon has taken up the fight against homelessness and poverty across the country as the founder of the Philadelphia Soul Charitable Foundation, while Matthew's j.k. livin foundation is working to bring after-school fitness and wellness programs to underserved communities nationwide.
