Justin Timberlake has beaten tireless campaigners Bono and Madonna to top a new list of celebrity philanthropists.
The SexyBack singer's continued work for the Shriners Hospital for Children has an annual impact of more than $9 million (£5.6 million), a figure that dwarfs Madonna's $5.5 million (£3.4 million) for Raising Malawi and Pamela Anderson's $4.8 million (£3 million) for People for the Ethical Treatment of Animals (PETA).
Media mogul Oprah Winfrey's work for her personal charity, Oprah's Angel Network, netted almost $4 million (£2.5 million), while U2 frontman Bono's annual impact on the ONE Foundation was estimated at $3.6 million (£2.25 million).
Angelina Jolie, Rihanna, George Clooney, Salma Hayek and Shakira also made it into the top 10.
