(CNN) -- David Bowie, whose incomparable sound and chameleon-like ability to reinvent himself made him a pop music fixture for more than four decades, has died. He was 69.
Bowie died Sunday after an 18-month battle with cancer, his publicist Steve Martin told CNN.
"David Bowie died peacefully today surrounded by his family after a courageous 18 month battle with cancer. While many of you will share in this loss, we ask that you respect the family's privacy during their time of grief," said a statement posted on his official social media accounts.
Neither his publicist nor the statement elaborated on what kind of cancer the singer was fighting.
Bowie's death has been the regular subject of Internet hoaxes for the last several years. So the news came as a shock to fans and industry insiders when it was confirmed.
"Very sorry and sad to say it's true. I'll be offline for a while. Love to all," his son, "Moon" film director Duncan Jones, tweeted.
Duncan Jones' mother, Bowie's first wife, Angela, was sequestered on the UK "Celebrity Big Brother." Producers posted Monday that she had been informed of his death off-camera and had chosen to stay on the show.
Bowie's wife of 24 years, fashion model Iman, had not released a statement as of Monday morning. On Friday she retweeted several birthday wishes to her husband.
British Prime Minister David Cameron expressed his sorrow to the press.
"Genius is an overused word but I think musically, creatively, artistically, David Bowie was a genius," he said. "He was a master of reinvention and one of the things that's so incredible is almost all his reinventions were incredible successes and worked brilliantly and so we mourn the loss of a great talent."
From a mop-topped unknown named David Jones, to his space-alien alter ego "Ziggy Stardust," to his dapper departure as the soul-influenced Thin White Duke, Bowie married music and fashion in a way few artists have been able to master.
He was theatrical, he was flamboyant, he was without parallel in his showmanship.
His albums, especially after his 1972 breakthrough "Ziggy Stardust and the Spiders from Mars," were treated as events. His songs, including "Changes," "Fame," "Heroes" and "Modern Love," were anthemic hits, played constantly on the radio and inspiring generations of musicians.
With a voice that soared from a baritone to a falsetto, he spoke of carrying on against the odds. Of the terror in knowing what the world is about. Of turning and facing the strange.
His songs were a salve for the alienated and the misfits of the world.
Bowie had just released his latest album, "Blackstar," on Friday, his 69th birthday. It shot to No. 1 on the iTunes chart in the UK and No. 2 in the United States, underscoring his appeal even after decades in the music business.
Like his past releases, the work -- generally praised by music critics -- defied genres. The influential music publication NME called it an amalgamation of "warped showtunes, skronking industrial rock, soulful balladeering, airy folk-pop, even hip-hop."
That in a nutshell was Bowie: There wasn't a musical style he didn't dabble in -- and indelibly leave his mark upon.
Since his breakthrough with 1972's "The Rise and Fall of Ziggy Stardust and the Spiders from Mars," Bowie's reach was eclectic: glam rock, prog rock, pop rock, electronic rock.
And the results? Electric. To the tune of more than 130 million records sold.
Though he didn't have his first No. 1 single in the United States until "Fame" in 1975, he'd already been making a mark with heavily played singles, including "Space Oddity," "Changes," "Suffragette City," "Rebel Rebel" and his first Top 40 hit, 1975's "Young Americans."
After that, he was almost as present on the singles charts as the album charts, with hits such as "Golden Years," "Under Pressure" (with Queen), "Let's Dance" (another No. 1), "Blue Jean" and "Never Let Me Down."
"David Bowie was one of my most important inspirations, so fearless, so creative, he gave us magic for a lifetime," tweeted rapper Kanye West, as news of Bowie's death made the rounds.
He was born David Jones, to a waitress and a nightclub owner in South London on January 8, 1947.
Though he began his musical life with his birth name, riding the mod wave of the mid-1960s, he changed to "Bowie" to avoid confusion with Davy Jones, the lead singer of the Monkees, who was enjoying serious pop success at the time.
That reinvention was the first of many. And his timing was often impeccable.
He released his song about a doomed astronaut, "Space Oddity," just days before the 1969 moon landing.
Four years later he killed off his most famous creation, the other-worldly "Ziggy Stardust," just at the point where it threatened to overwhelm him.
He then transformed into the Thin White Duke, a cocksure but coked-out mad aristrocrat. While Ziggy was all arena rock, the Duke was chilled soul. While Ziggy gave him "Space Oddity," the Duke gave him yet another timeless classic, "Fame," a song co-written with John Lennon, one of his many admirers.
With Bowie, it was difficult to separate art from reality. And as the drug-taking took its toll, he holed up in Berlin and recorded the groundbreaking "Berlin" trilogy: "Low," " 'Heroes' " and "Lodger." (The quotation marks around " 'Heroes' " were a deliberate ironic touch.)
Musically, he kept one foot in the avant garde. On the song "Heroes," he half-sings, half-screams, with some of the atmosphere provided by white noise.
Others paid attention. Composer Philip Glass used "Low" and " 'Heroes' " as the subjects of symphonies in the 1990s.
"David Bowie was a true innovator, a true creative. May he rest in peace," tweeted uber-producer Pharrell Williams.
Despite the edginess, Bowie's work still resonated with the mainstream. "Heroes," in fact, later became a theme for many. The 2012 British Olympic team entered the stadium to the tune.
He even sang a Christmas song, "The Little Drummer Boy," with the most mainstream of American crooners, Bing Crosby, on a 1977 TV special. There were no theatrics, no frills, just Bowie's pure voice meshing with one of the oldest of the Old Guard.
The '80s and beyond
The 1980s were a great time to be Bowie.
Starting with his collaboration with Queen on "Under Pressure," he brilliantly reinvented himself to take full advantage of the video music era.
The 1983 "Let's Dance" album, produced by Chic's Nile Rodgers, became his most commercially successful album, its sound and his look influencing a new generation of musicians. The videos for the album's singles, including the title cut and "China Girl," were ubiquitous on the music video channel MTV.
Bowie, by then pushing 40, was as relevant as the era's power chord-slamming 20-somethings or synthesizer-playing Euro pop stars -- musicians for whom he'd paved the way.
Through it all, his Midas touch made classics of other people's songs. He produced Lou Reed's "Transformer," with its hit "Walk on the Wild Side," and Iggy Pop's "Lust for Life," among others.
"David's friendship was the light of my life. I never met such a brilliant person. He was the best there is," Iggy Pop tweeted.
Bowie's output thinned in the 1990s and the 2000s, but he was no less envelope-pushing. He experimented with heavy metal, with industrial rock, and with drum and bass.
Bowie's theatricality wasn't limited to performing on stage. In 1976 he played the lead in Nicholas Roeg's film "The Man Who Fell to Earth" as -- perhaps appropriately -- an alien. Four years later, he portrayed Joseph Merrick, who'd been deformed by a medical condition, in Broadway's "The Elephant Man."
Bowie continued acting through most of his life, often drawn to unusual characters. He played a vampire in 1983's "The Hunger," the Goblin King in 1986's "Labyrinth," Pontius Pilate in 1988's "The Last Temptation of Christ" and Andy Warhol (about whom Bowie had once written a song) in 1996's "Basquiat."
He wasn't above a little comedy, however. He had cameos in TV shows such as "SpongeBob SquarePants" and "Extras" and played himself in 2001's "Zoolander."
His androgynous look sometimes led to questions of his sexuality that, like his music, defied classification.
He told Playboy magazine in the 1970s that he was bisexual. He told Rolling Stone in the 1980s he had always been a "closet heterosexual."
In 1992, Bowie married his second wife, model Iman. They have a daughter, Alexandria, together.
Bowie had some health problems in the early 2000s, including an emergency angioplasty in 2004.
He also ceased touring after the "A Reality" tour in 2003-04 and, until 2013's "The Next Day," he hadn't put out an album in 10 years.
But recent months had seen signs of a Bowie re-emergence. Aside from "The Next Day," he co-wrote the current stage play "Lazarus," based on "The Man Who Fell to Earth," and recorded and released "Blackstar."
As usual, he gave it his all.
"He'd just go from zero to 60 once we walked out of the control room and into the studio," drummer Mark Guiliana told Rolling Stone about the "Blackstar" sessions. "And his vocal performances were always just stunning, amazing."
He was always busy, always on to the next thing.
Twenty years ago, interviewed by Mick Brown of the UK Telegraph, he coolly assessed his past, but -- typically Bowie -- looked to the future.
At the time, he was reveling in the paintings of Damien Hirst and had plans for another project with producer Brian Eno. And there was no sense in waiting, he said.
"I don't like wasting time," Bowie told the paper.
Bowie is survived by two children, Duncan and Alexandria, and his wife, Iman.
