The Hollywood superstar's mother recently penned a letter to her local newspaper touting her support for Republican presidential candidate Mitt Romney, and her disdain for abortion and same-sex marriage.
Jane Pitt's views, which appeared in Springfield, Missouri's News-Leader Tuesday, could not be further removed from those of her liberal son.
The actor has been a vocal gay rights advocate who famously said he would not marry fiancée Angelina Jolie until it was an option for all people, regardless of their sexuality.
Jane Pitt's missive was written in response to another letter published in the newspaper which expressed support for Christians who do not to vote for Romney because of his Mormon beliefs.
Mama Pitt hit back saying: "any Christian should spend much time in prayer before refusing to vote for a family man with high morals, business experience, who is against abortion, and shares Christian conviction concerning homosexuality just because he is a Mormon."
The News-Leader initially denied the letter was written by the Oscar-nominated star's mother, but later amended an editor's note to confirm it was.
"Any Christian who does not vote or writes in a name is casting a vote for Romney's opponent, Barack Hussein Obama," Jane Pitt continues in her letter, identifying herself as a a Christian who differs with the Mormon religion.
Obama is "a man who sat in Jeremiah Wright's church for years, did not hold a public ceremony to mark the National Day of Prayer, and is a liberal who supports the killing of unborn babies and same-sex marriage," she says before reminding readers that voting is a "sacred privilege and a serious responsibility."
