A DNA test revealed the shock truth for lovers Paul and Lee, who had been a couple for years after coming across each other online.

The pair – who exchanged flirty messages for a full two years before hooking-up – were none the wiser to the fact they shared the same mother…and were in fact closer than either of them could ever have imagined.

The reality only came to light when Lee’s family and friends first met his new lover and noticed a striking similarity between Paul and his mother’s former husband, Ron.
