The model recently reunited with O'Hara, the Tottenham Hotspur midfielder and father of her child Archie, despite reportedly calling off their planned wedding.
Llloyd told today's New magazine: "He got angry because there was stuff in magazines saying Jamie had done this and that. Someone started a rumour saying I've cheated on Jamie. I was like, 'Where do these rumours come from?' It annoys us."
She added of her and O'Hara's Christmas plans: "We've got both of our families coming over and we're going to take them out to a restaurant so no one has to clean up. We've got Archie a Father Christmas outfit to wear on the day."
