Who are the greatest celebrity do gooders? With the help of DoSomething.org, VH1 will examine lists of hundreds of philanthropic stars from data compiled by established research institutions, and then narrow the list down to the 20 celebrities that have had the most charitable impact.We just received confirmation from a VH1 staff member that the Jonas Brothers have made this list. We don’t know which exact spot they hold but they are definitely on it. Watch this Thursday 11/19 to find out. Check your local listings for a time.
