A source said: 'He is in talks to turn Austin Powers into a musical stage show.
'Mike would be heavily involved in writing the show, but he will not star in it, even though he has quite a good singing voice.'
It follows reports that Myers, 48, has inked a deal with production company New Line to make a fourth Austin Powers flick.
A source told the New York Post: 'The deal is in place, and Mike is currently writing the new Austin Powers film. But no date has yet been set to start filming. It is not yet clear if this will be a 2013 or 2014 release.'
The three Austin Powers films - 1997's Austin Powers: International Man of Mystery, The Spy Who Shagged Me, which hit screens in 1999 and 2002's Goldmember - have grossed more than $676 million USD worldwide.
A spokesperson for Myers was unavailable for comment.
