Brad Pitt's mother has astounded the movie star's fans by writing an anti-President Barack Obama essay for her local Missouri newspaper.

Jane Pitt doesn't support her son and daughter-in-law-to-be Angelina Jolie's liberal sensibilities and that has been made clear in a letter printed in The Springfield News-Leader.

Urging her fellow Christians to vote for the President's Republican rival Mitt Romney in November, Mrs. Pitt calls Obama "a liberal who supports the killing of unborn babies and same-sex marriage."

And Jane insists Obama is the wrong man to be running the country, adding, "Any Christian who does not vote or writes in a name (that isn't Romney's) is casting a vote for Romney's opponent, Barack Hussein Obama - a man who... did not hold a public ceremony to mark the National Day of Prayer."

Her stance comes just a few months after her son opened up about his support for Obama in a candid cover story for The Hollywood Reporter.

Newspaper editors have confirmed the letter to the News-Leader was written by the movie star's mother after some initial confusion.

An editor's note reads: "The News-Leader has verified the letter writer is the mother of actor Brad Pitt and local businessman Doug Pitt."
