And the award for the most charitable celebrity of 2013 goes to... Taylor Swift for the second year in the row!
"(She) turned her 24th birthday into a gift for others, quietly donating $100,000 of her own money to The Nashville Symphony," said DoSomething.org, which compiled the annual list.
DoSomething.org is the largest non-profit organisation for young people and social change in the US.
UK boy band One Direction made their debut on the list in second place thanks to their volunteer trip to Ghana as part of their efforts with the UK charity Comic Relief, while US pop star Beyonce took the third spot.
