British astronaut Tim Peake tweeted his sadness from outer space aboard the International Space Station.
Saddened to hear David Bowie has lost his battle with cancer - his music was an inspiration to many. @DavidBowieReal— Tim Peake (@astro_timpeake) January 11, 2016
London Mayor Boris Johnson said "No-one in our age has better deserved to be called a genius."
Archbishop of Canterbury Justin Welby told the BBC today that he became a fan during Bowie's early rise to prominence.
"I remember sitting listening to his songs endlessly in the '70s particularly and always really relishing what he was, what he did, the impact he had," Welby said. "Extraordinary person."
Comedian Ricky Gervais, who persuaded his idol to appear on his television show, "Extras," wrote on Twitter:
I just lost a hero. RIP David Bowie.— Ricky Gervais (@rickygervais) January 11, 2016
