Angelina Jolie and Jane Pitt.

Brad Pitt's mother Jane Pitt has ''Christian'' views on abortion and gay marriage.

The showbiz matriarch - whose son Brad is one of the most vocal supporters of gay rights in Hollywood - has written a letter to her local newspaper the News-Leader in Springfield, Missouri, urging people to vote for Republican presidential candidate Mitt Romney, due to him being a ''family man with high morals''.

She also hits out at US President Barack Obama because he supports the ''killing of unborn babies and same-sex marriage''.

She wrote: ''I am ... a Christian and differ with the Mormon religion. But I think 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.

''Any Christian who does not vote or writes in a name is casting a vote for Romney's opponent, Barack Hussein Obama - 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.''

Brad - who is engaged to Angelina Jolie - has previously taken part in a play about gay rights alongside George Clooney, and hinted he would not marry the actress until all Americans, including homosexuals, have the right to wed.
