UPDATE: 9:04 p.m. EDT — TMZ, which broke the news of Prince's death early Thursday, said multiple sources had confirmed the singer was treated for a drug overdose less than a week before he died. While a representative said Prince was battling the flu, unnamed sources told TMZ late Thursday that he was rushed to a hospital last week for a "save shot," a procedure typically used to counter the effects of an opiate. He was told to stay in the hospital for 24 hours, but left because he couldn't get a private room. The report was not confirmed. 

UPDATE: 4:44 p.m. EDT — The NAACP joined the chorus of condolences upon learning of Prince's death, calling him a "genius" and "groundbreaking," noting he was just the third artist in the history of the renowned civil rights organization's existence to receive its Vanguard Award that recognizes "artistic innovation."

The NAACP's statement in full follows below.

The National Association for the Advancement of Colored People mourns and celebrates the life of Prince Rogers Nelson, an artistic genius whose work transcended boundaries and united people through the power of music. A multi-NAACP Image Awards winner, Oscar winning composer, Grammy winner, celebrated producer, singer, and songwriter, Prince used his prodigious songwriting talents to preach messages of love, acceptance, and pride while defying the expectations and limitations of record labels, the media, and society.

His groundbreaking work spurred the NAACP to name Prince as only the third artist in the Association’s 107-year history to receive the NAACP Vanguard Award for artistic innovation at the 2005 Image Awards. The NAACP Vanguard Award is presented to a person whose groundbreaking work increases our understanding and awareness of racial and social issues. Previous recipients are Stanley Kramer and Steven Spielberg.

Prince was an uncompromising artist who used his talent to spur kindness and self-determination. We hope his immense body of work will continue to influence future generations to “make this cruel, cruel world hear what we’ve got to say, put the right letters together, and make a better day.”
