A 22-year-old funeral worker, Declan Fuller, says he split from his wife after catching her cheating with his father – and the pair are now expecting twins.
Fuller, who hails from Rhondda in South Wales, claims he saw his ex, Stephanie, also 22, going into a bedroom with his 44-year-old father, Darren.
According to him, when he asked Stephanie what had happened she simply said: ‘We were watching The Simpsons on TV.’
His father and Stephanie – who is now pregnant – are living together around six miles away from his residence.
But Stephanie insists in an interview with The Sun UK that she was never unfaithful to her ex.
‘I did not cheat on Declan. We got together with his father a week or so after he left me.’
However, Declan said: ‘It’s like a plot from EastEnders. It’s not normal. I feel betrayed but I’m better off without the two of them.’
He said that he became suspicious after his father, who is divorced, moved in with him, Stephanie and their two-year-old daughter Willow last September.
Declared said that two months later, he checked the baby monitor, which he had trained on his father’s door only to discover the abominable.
Stephanie’s babies will be Declan’s half brother or sister and Willow’s half brother or sister and also her aunt or uncle.
His father, Darren, who refused to comment, will be both Willow’s grandfather and stepfather if he eventually marries Stephanie.
