this is from popbitch, so take it with so much less than a grain of salt...

"Madonna is looking at covering Bowie's Starman as the theme to an animated film version of a new children's book that she's writing."

ok, let the catfights begin...

what's that line from 'ghostbusters' about dogs and cats having sex in the street?

This is so a rumor.
She was apparently going to cover one of his songs for her last album and that never materialized.
I doubt she will make music for her animated film as well...

In 2002,there was a rumor that she was gonna record a remake of Bowie's "Ziggy Stardust" for inclusion on 'American Life'.It never materialized.

I'd much prefer a cover of "Starman". No one should ever cover Ziggy.

i don't really think its true but i do wonder why these rumours of a bowie cover keep surfacing.
