Trump denied these claims, and in April 2018, Daniels filed a lawsuit against the president on defamation charges for calling her statements lies.
Insiders told the publication she fell out with bosses on the show after she demanded a whopping £100,000 extra on top of her record £750,00 pay cheque, which she was reportedly set to receive after one week in the house.
A TV source told The Sun: "Stormy landed in London and was taken to the Village hotel in Elstree where the celebs are put up".
'From the outset it was clear something was wrong and once she sat down with the producers all hell broke loose.
"They tried everything to persuade her to stay and no one could work out why she'd fly all the way from the United States to London before deciding to drop out".
She said she had "closed that chapter" of her life and was looking forward to entering the CBB house.
Daniels alleges that Trump paid "hush money" to silence her about the affair and said she was "threatened" to sign a non-disclosure agreement. "That massive mock-up of the White House was all for Stormy", said the source.
"To say it's been a nightmare is an absolute understatement".
Representatives of Channel 5 and Stormy Daniels declined to comment when asked by Express.co.uk.
The 3adult movie actress who claims to have slept with U.S. President Donald Trump shortly after his 2005 marriage to the First Lady, Melania Trump, will enter the Big Brother house on Thursday (16Aug18) alongside 12 other famous faces, including ex-Cheers actress Kirstie Alley, former Liverpool and England soccer player Jermaine Pennant and Love Island star Gabby Allen.
Usually, the carefully selected line-up appears behind an automatic door before walking down a runway, posing for photos, before joining host Emma Willis.
There was a noticeable presence missing from last night's show though - Stormy Daniels.
Former Coronation Street star Ryan Thomas was the second star to enter the house, and when he saw Alley, he shouted: "Look who's talking now!"
According to Channel 5, the official description of this season's house reads, "Any celebrity wrapped up in a media storm needs a quick getaway from the pressures of the scrutiny and what better place to go than the sunny climes of California".
