Russell Brand took to his YouTube channel on Friday to 'absolutely deny' what he called 'serious allegations' made against him in a letter and email - ahead of a mystery Channel 4 Dispatches investigation.
The much-anticipated programme is set to air at 9pm on Saturday night, with speculation building over who or what could be at the centre of the investigation.
Sources say that the long running current affairs documentary series will feature details about a well-known celebrity, which the Mail have been told are shocking.
Though there is no indication Brand will be covered in the programme, he made a video addresses his fans.
The comedian, actor and internet personality told his 6.5 million subscribers late on Friday night that there are 'very, very serious criminal allegations' made against him which he 'absolutely refutes'.
Brand said he had received two 'extremely disturbing letters' from a 'mainstream media TV company' and a newspaper.
The letters listed 'a litany of extremely egregious and aggressive attacks, which are untrue', Brand said.
