"My heart is overcome with sadness for the devastating loss of my true friend Michael. He was an extraordinary friend, artist and contributor to the world. I join his family and his fans in celebrating his incredible life and mourning his untimely passing."

-- Pop star Madonna told People magazine: "I can't stop crying over the sad news ... I have always admired Michael Jackson. The world has lost one of the greats but his music will live on forever. My heart goes out to his 3 children and other members of his family. God bless."

-- Representatives for actress Elizabeth Taylor, another of the singer's longtime friends, said she was "too devastated by the passing of her dear friend Michael Jackson to issue a statement at this time" but promised one later.

-- Former Guns N' Roses guitarist Slash, who performed Jackson's 1991 hit "Black or White," said: "Really sad news about Michael. He was talent from on high."

-- Entertainer Liza Minnelli told Entertainment Tonight: "He was a kind, genuine and wonderful man. He was also one of the greatest entertainers that ever lived. I loved him very much and I will miss him every remaining day of my life."

-- Neil Portnow, president and CEO of the Recording Academy, the group that organizes the Grammy Awards, said in a statement:

"Rarely has the world received a gift with the magnitude of artistry, talent and vision as Michael Jackson. He was a true musical icon whose identifiable voice, innovative dance moves, stunning musical versatility and sheer star power carried him from childhood to world wide acclaim.

"A 13-time Grammy recipient, Michael's career transcends musical and cultural genres and his contributions will always keep him in our hearts and memories."

-- Rudy Clay, mayor of Jackson's hometown, Gary, Indiana, called Jackson the "world's greatest entertainer," who had made Gary proud.

"Wherever a person from Gary, Indiana, went in the world, people would say, 'That's Michael Jackson's home town.' So Michael helped Gary just by being from Gary," Clay told the Chicago Tribune.
