Steve Rannazzisi, who stars in popular series The League, told interviewers repeatedly that in 2001 he had dramatically escaped from the World Trade Centre after a plane hit the North Tower.
He even attributed his success to the attacks - where 3,000 people lost their lives - saying they made him realise what was important in life.
But as it turns out, Steve Rannazzisi was not in the World Trade Centre at all.
Despite repeatedly telling the same story, Rannazzisi has now shockingly admitted he fabricated the ENTIRE THING.
Questions were raised when there was no record of Steve in the South Tower on 9/11. Then the comedian was forced to admit it was all lies, taking to Twitter to express his guilt.
‘I don’t know why I said this. This was inexcusable. I am truly, truly sorry,’ he wrote on Wednesday.
‘For many years, more than anything, I have wished that, with silence, I could somehow erase a story told by an immature young man. It only made me more ashamed.’
He added: ‘It was profoundly disrespectful to those who perished and those who lost loved ones.’
Describing his experience on 9/11, Steve said in 2009: ‘I was there and then the first tower was hit and we were like jostled all over the place.’
‘I went downstairs, walked outside, saw the pandemonium, and then five or six minutes later it was like bam.’
‘I still have dreams, you know those falling dreams,’ Steve had the audacity to add.
Understandably, Twitter users reacted with anger at Steve’s admission, with one suggesting he should donate his wealth to actual 9/11 survivors.
Another said: ‘It was disrespectful to everyone on planet earth. Not just the victims. U R A Shameful Tool (sic).’
One other user also added: ‘You fraud. I know people that died that day. And it was 6 years. You weren’t a young man man. Fraud.’
