Klass recently alleged that a newly-married Hollywood star tried to get her to sleep with him and sign a confidentiality agreement six months ago.
Klass has now added that the well-known actor put a lot of planning into the proposal before the two met for their lunch meeting, according to The Sun.
She said: "I turned up and there were bodyguards and a PA brandishing the contract. He knew so much about me. He did his research well."
In July, the model claimed to have been offered "more than the interview" by three top stars, including one that would "bring down Hollywood if the story ever got out".
Klass's CNN colleague Piers Morgan has apparently begged the 32-year-old to name the actor at the centre of the controversy.
