The actress/singer was reportedly dumped from the project in May (11) but she appeared on TV and insisted the story was bogus.
Duff told Access Hollywood Live she called director Tonya Holly for clarification when the report broke and was told she had not been fired and was still expected to play bank robber Bonnie Parker, opposite Kevin Zegers, in the film.
But now it looks like both Duff, who announced her pregnancy earlier this month (Aug11), and Zegers will both be replaced - the actor reportedly has a scheduling conflict.
A source close to the production tells WENN Amanda Seyfried and James McAvoy have been offered roles in the film - a remake of the cult 1967 film, starring Warren Beatty and Faye Dunaway.
The source insists the split between Holly and Duff was amicable, telling TMZ.com, "Hilary won’t be available until next June."
Shooting is scheduled for later this year (11).
