Ben Affleck is due to hand out the grand prize at the Do Something Awards this weekend.
The 'Argo' actor will honour a dedicated youth activist on Sunday evening (12.08.12) with a $100,000 prize in Santa Monica, California and the show will be televised August 21 on VH1.
According to website UsMagazine.com, the father of three is most dedicated to fostering development opportunities for residents of the war-torn Eastern Congo.
In 2009, he founded the Eastern Congo Initiative to help with the serious cause.
His wife Jennifer Garner recently said she is evolving as a mother.
The 40-year-old actress has three children, Violet, six, Seraphina, three, and five-month-old Samuel, with Ben and admits she has become more relaxed with the arrival of each child.
Jennifer - who plays mother Cindy Green in new movie 'The Odd Life of Timothy Green' - said: ''It (motherhood) evolves all the time. With my first child, I was a little more like Cindy Green in this movie who is just obsessively trying to make sure her child is happy at every moment ... as many first time mums can be. Then you kind of learn to let go of some of that, you chill out a bit.''
