Actress Angelina Jolie has reportedly been left furious after her boyfriend Brad Pitt’s mother Jane insisted on buying girly clothes for her notoriously tomboyish granddaughter Shiloh.

Despite Shiloh Jolie-Pitt and her five siblings being allowed to choose their own clothes by their famous parents, Jane Pitt is said to have purchased a series of feminine outfits for the six-year-old.

According to the Evening Standard, Angelina Jolie found Jane Pitt’s move “disrespectful” for her to buy such clothes for Shiloh, considering it is well known that she likes to dress in similar style to her brothers.

A source told the newspaper: “It’s well documented that Shiloh likes to dress like a boy.

“But Jane still insists on buying her fairy costumes and princess dresses, which Angelina finds very disrespectful.”

It is the second time this year that Angelina Jolie has been left angry by Jane Pitt, after Brad’s mother wrote a letter to a local newspaper in the United States urging Americans to vote against President Barack Obama in the upcoming elections because of his support for gay marriage.

In a letter to the Springfield News-Leader in Missouri urging support for Republican candidate Mitt Romney, Jane Pitt wrote: “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.”

Angelina Jolie and Brad Pitt, who are prominent supporters of gay marriage and President Barack Obama, were said to be appalled by the letter.

They once said they would not marry until same-sex marriage was legalized in the US, but became engaged after pressure from their six children.

The source said: “Brad and Angelina were devastated by Jane’s actions. They have worked hard campaigning for equality, working closely with Barack Obama.

“Angelina called Jane and told her she believes she’s setting a bad example for the kids.”

A source told Star magazine at the time of the letter: “Jane has never wanted to talk politics with Angelina.

“She knew it would cause greater issues for them, and she wanted to try to have a relationship with the mother of her grandkids. She never thought her letter would be such a big deal.”

Brad Pitt once said of his mother’s outspoken views: “She’s very loving, very open, genuine, and it’s hilarious because she always gets painted as a she-devil.”

There were once rumors that Jane Pitt and husband Bill did not get along with their son’s long-term partner, favoring his ex-wife Jennifer Aniston instead.

But such myths were dispelled when they stepped out together in December last year to support Angelina Jolie at the premiere of her first venture in the director’s chair, In the Land of Blood and Honey.
