For 21 years, Andy Phillips (right) believed that Jordan was his son. When the baby was born, he held him in his arms and loved him. But two years ago, Jordan arrived on his doorstep and told him the result of a DNA test: 'You're not my dad.' That devastating moment marked the beginning of two hellish years for Andy, during which he has struggled to understand why he was so terribly deceived by Jordan's mother, 42-year-old Andrea Roberts. All three are pictured inset.
He remembers buying him his first drum kit and watching amazed as his little boy immediately beat in perfect time to Hey Jude! by The Beatles.
Overriding all of these happy memories, however, is the terrible day, two years ago, when a 21-year-old Jordan turned up on Andy's doorstep in Telford, Shropshire, with a piece of paper in his back pocket.
'It was a DNA test,' recalls 43-year-old Andy. 'Jordan said there was something he had to tell me. He paused, and then he said: "You're not my dad." '
That devastating moment marked the beginning of two hellish years for Andy, during which he has struggled to understand why he was so terribly deceived by Jordan's mother, 42-year-old Andrea Roberts.
Forced to pay child maintenance after they separated when Jordan was seven, Andy believes that Andrea suspected for years that the boy was not really his son.
And while Andrea this week agreed to pay Andy £19,000 in a last-minute out-of-court legal settlement after he brought a claim for the psychological damage her deceit has caused him, Andy says there are no victors in this sorry story - least of all Jordan, who has been bounced between his warring 'parents'.
Indeed, the court case has caused such bitterness that Jordan, now 23 and a drummer in a band, is no longer speaking to the man he once called Dad, despite Andy's insistence he still loves him like a son.
'He doesn't want to know me,' Andy says. 'It's as if I've lost him twice over.'
While Andy, an engineer, is still undergoing counselling to cope with the trauma of discovering that Jordan is not his son, Andrea says she too has suffered. She insists she didn't know for certain that Jordan was not Andy's son until a DNA test in October 2011 confirmed the truth. 'I was 18,' she told the Mail. 'I can't believe that what happened when I was so young is still haunting me all these years later.'

In a heartfelt letter she sent to Andy after he discovered the truth two years ago, she wrote: 'I truly didn't have a plan at 18 years old, but as a terrified, immature, confused girl whose own father turned his back on me, I took each day and tried to do what was best at the time. You and I were together and that's how I wanted it to be. I'm not a bad person and wouldn't want to hurt anyone.'
In yet another twist to the story, she is now in a relationship with Jordan's biological father - her former childhood sweetheart.
So how did this confused and sad state of affairs come to pass? According to legal documents seen by the Mail, the seeds of deceit were sown almost right from the start of Andy and Andrea's relationship.
They met in a pub in Glossop in Derbyshire in the summer of 1989 when Andrea was 17 and Andy 19. They had gone to the same comprehensive in the town but barely remembered each other from their schooldays.
