( CNN ) -- Add R & B star Usher to the list of entertainers giving up the paychecks they earned performing for members of embattled Libyan leader Moammar Gadhafi 's family . `` I am sincerely troubled to learn about the circumstances surrounding the Nikki Beach St. Bart 's event that took place on New Year 's Eve 2009 , `` Usher said in a statement Monday . `` I will be donating all of my personal proceeds from that event to various human rights organizations . '' According to U.S. diplomatic cables posted by WikiLeaks , the Caribbean island was the site for a New Year 's Eve party thrown by Mutassim Gadhafi , Libya 's national security advisor and one of the dictator 's sons . Usher , along with Beyonce , were the entertainment in what the cables called a $ 1 million personal concert . Beyonce said through a representative last week that she had donated the money she received to earthquake relief in Haiti . The same Gadhafi son on the same island a year earlier paid $ 1 million to hear Mariah Carey sing on New Year 's Eve 2008 , the cables said . She sang four songs . In a statement released last week , Carey said she was `` naive and unaware of who I was booked to perform for . I feel horrible and embarrassed to have participated in this mess .

Ultimately we as artists are to be held accountable .
