George Clooney has described the Daily Mail as the "worst kind of tabloid", as he rejected the Mail Online's apology for a story about his upcoming marriage.
The Mail Online apologised to the actor after publishing an article claiming his fiancee's mother opposed their marriage on religious grounds.
Clooney said the Mail's claim that the original story was "not a fabrication" was not true, and that the paper was either "lying originally or they're lying now".
Writing in the USA Today, Clooney said: "I thank the Mail for its apology. Not that I would ever accept it, but because in doing so they've exposed themselves as the worst kind of tabloid.
"One that makes up its facts to the detriment of its readers and to all the publications that blindly reprint them."
The Mail Online website has apologised to George Clooney and promised a full investigation into a story that claimed his fiance's mother did not approve of his upcoming marriage.
In a statement they said: "The MailOnline story was not a fabrication but supplied in good faith by a reputable and trusted freelance journalist."
They added: "We only became aware of Mr Clooney’s concerns this morning and have launched a full investigation. However, we accept Mr Clooney’s assurance that the story is inaccurate and we apologise to him, Miss Amal Alamuddin and her mother, Baria, for any distress caused."
In an earlier article for the USA Today newspaper, the Gravity star accused the Daily Mail newspaper of printing a "completely fabricated" story about his fiance's mother opposing their forthcoming marriage for religious reasons.
