David Bowie has denied reports he is to star in BBC show Doctor Who, rubbishing the claims as "absolute tish and tosh".
Bowie played himself in the BBC comedy Extras
Tabloid newspaper The Sun reported that the 60-year-old singer was set to play an evil alien abductor in a two-part special planned for next year.
A statement on Bowie's website says the show's producers previously approached him about a cameo role in the series in the Eighties, but he declined.
Bowie played an alien in the 1976 film, The Man Who Fell to Earth.
According to the newspaper, Bowie had agreed to play an alien who kidnaps crime author Agatha Christie - who in real life mysteriously disappeared for 11 days in 1926.
A spokeswoman for the BBC One show also denied the story.
Last year Bowie voiced a character for cult children's TV series SpongeBob SquarePants and appeared as himself in Ricky Gervais's comedy series, Extras.
