England polo player James Carr, 25, insists he had sex with 40-year-old at him home, after they met at Ascot in March this year.
James, who was living with friends opposite Carla and Jeremy’s home, told The Sun: “Carla called after midnight asking if I wanted to meet her outside for a cigarette.
“We had a smoke and a chat and she told me Jeremy was in America. Then suddenly we began kissing. Without talking, I took her hand and led her inside my house.
“Carla took her high heels off so her shoes wouldn’t make a noise on our stone stars. We didn’t want to wake my housemates. We started having sex – it was amazing.”
But, after ‘six or seven’ secret meetings, James and Carla were forced to end their affair, when news started to spread around their village in Berkshire.
Last week Jeremy, 50, released a statement confirming his and Carla’s plans to divorce.
It read: “After 13 years of a generally happy marriage, my wife and I, Carla, have separated amicably.”
Jeremy and Carla have two daughters and a son, and he has another daughter from a previous marriage.
