George Clooney is known for being private when it comes to his personal life, so when he does open up, it is for a good reason.

The Oscar-winning actor could not hold back when the U.K.'s Daily Mail published a false story on Monday (July 7th) about his fiancé's mother opposing their upcoming wedding.

News broke of Clooney becoming engaged to British lawyer Amal Alamuddin in April, and they are reportedly set to tie the knot in Lake Como, Italy, this fall.

The 'Gravity' star was so angered by the Daily Mail's fallacious claims, he penned an op-ed for USA Today, slamming the British tabloid.

"The Daily Mail has printed a completely fabricated story about my fiancée's mother opposing our marriage for religious reasons," Clooney wrote.

Adding, "It says Amal's mother has been telling 'half of Beirut' that she's against the wedding. It says they joke about traditions in the Druze religion that end up with the death of the bride. Let me repeat that: the death of the bride. First of all, none of the story is factually true."

Baria Alamuddin, the mother of the bride-to-be, is not part of any religion, according to Clooney, and reiterates that she has never opposed their nuptials.

"But this lie involves larger issues," the Hollywood hunk continued. "The irresponsibility, in this day and age, to exploit religious differences where none exist, is at the very least negligent and more appropriately dangerous. We have family members all over the world, and the idea that someone would inflame any part of that world for the sole reason of selling papers should be criminal."

This ruthless article did get the response it wanted as the Daily Mail took down the false story, and issued an apology to Clooney, on Wednesday (July 9th).

The newspaper said it was "supplied in good faith by a reputable and trusted freelance journalist," according to the Associated Press. "We accept Mr. Clooney's assurance that the story is inaccurate and we apologize to him, Miss Amal Alamuddin and her mother, Baria, for any distress caused," the statement continued.
