Lee was left reeling when Jessica Keevil, who he met in a club, recently told him he fathered her 2-year-old daughter.
He received the DNA confirmation last week.
‘Lee is the father of the child,’ says his spokesman.
‘He is now sorting out access and child support. This has come as a huge surprise, but he will 100% be part of the child’s life from here on.’
Lee is already dad to 11-month-old Rayn with fiancée Samantha Miller.
‘I will definitely be a part of my daughter’s life,’ he tells the Daily Mirror.
‘But I would appreciate it if everyone could respect this is a private matter.’
