Soul legend Aretha Franklin is giving fans the chance to win private singing lessons with the star in a new charity auction.
Franklin's one-on-one vocal session is just one of a number of exclusive prizes available online at charitybuzz.com, with profits benefitting the Robert F. Kennedy Center for Justice and Human Rights.
Stevie Wonder has donated his harmonica for the sale, while bidders can also make offers on dinner with comedian Bill Cosby, a visit to the Desperate Housewives set, swimming lessons from Olympic champion Michael Phelps and a meet and greet with Oprah Winfrey and win VIP tickets to her daily talk show.
The auction closes on 28 May (09).
