Did one of President Barack Obama's biggest celebrity fans drop out of an upcoming film with actor and director Clint Eastwood?

Variety reports that Beyonce Knowles has dropped out of the unmade Eastwood flick "A Star is Born," citing scheduling conflicts, according to their sources.

The R&B singer recently hosted a mega fundraising bash with her husband, rapper Jay-Z on behalf of Obama's campaign last month. And Beyonce also sang Etta James' "At Last" for the Obamas "first dance" during the 2009 Inauguration.

Eastwood, who will direct the remake of the 1976 rock musical film, was cast into the lime light for a different reason in August. During a surprise appearance at the Republican National Convention, Eastwood delivered a rambling speech in which he spoke at length to a chair intended to represent an "invisible Obama."

Beyonce was set to star in the upcoming film in the role once played by Barbara Streisand and by Judy Garland in 1954.

The filmmaker has reportedly not yet settled on a male lead for the film.

Knowles' publicist did not immediately return ABC News' request for comment.
