Fans of CBB will know Tiffany caused havoc when she misunderstood Angie Bowie telling her that her ex-husband David Bowie had died. Tiffany had thought Angie had meant David Gest - who was actually living in the house with them - had passed away instead and the fallout from her mistake saw her clash hugely with her housemates.
Appearing on This Morning, Tiff addressed her mix-up once again, admitting she was "so embarrassed" to have got things so wrong.
She told hosts Phillip Schofield and Holly Willoughby: "You guys can understand this. We don't get the paper in there, so the next closest thing to David in my head is David Gest. He was suffering from a bit of a cough so I just thought maybe the cold had killed him?"
She had been joined by Danniella Westbrook on the show and the former EastEnders actress added in Tiffany's defence: "He had pneumonia, he was very poorly. We had all taken turns - the bits you don't see - getting up in the night and seeing to him."
While Phillip said he could understand Tiffany's mistake, he asked her why she couldn't let the misunderstanding go. Tiffany fell out with the rest of the house, after refusing to apologise to Angie for her mistake.
"I was just so stubborn, wasn't I? I was so ashamed," Tiffany admitted. "I felt so embarrassed and I was so totally wrong and my pride - it just got too big to swallow. I should have said I was sorry, but Ange - we've made up since then."
Viewers saw Tiffany offer Angie an apology when recalling her time in the CBB house during her last night on the show - admitting the mix-up had been her lowest point on the show.
Tiffany went on to finish fourth place on CBB. Darren Day came third, Stephanie Davis was voted in second and Geordie Shore star Scotty T was this series' winner.
Looking back on the whole experience, Tiffany admitted taking part in Celebrity Big Brother has helped her to 'grow up.'
She said: "I don't kick off as quickly as I used to. It really taught me how to live with strangers."
