Party boy Calum Best was left stunned when he was faced with a woman who claims that her four-year-old daughter is his child.
Little Amelia Best Hogan (4) was brought by her mum Lorna to meet Calum at the launch of his aftershave at a pharmacy in Bundoran, Co Donegal.
However, Calum walked off when approached by the woman who claims her daughter is a result of a fling with Calum.
She handed him a letter which was signed from Amelia which read: "Please daddy, take the DNA test so you don't have to deny me anymore. I'm your daughter. Please have a heart and don't put me through this anymore.
"I see you on TV and in the papers. I say, 'That's my daddy, when can I see him mummy?' Mummy tells me what a great person my grandad was too. It's not my fault. I'm only four-and-a-half. I want to meet you so much... Please. Until we meet. Your daughter, Amelia XXX".
Calum, who had a reputation as a dedicated ladies man, was recently courting Irish model Georgia Salpa.
However, she split with the lothario after photos emerged of him returning to the North London home of TV presenter Donna Air, following a night out.
Lorna said: "I got hold of Amelia and I just walked straight in. I said, 'Can I just give this letter to Calum?'
"I had to put Amelia down to get through the men because they wouldn't let me through. Calum then got up to leave. So I thought, forget this. I stormed right through and shouted, 'Calum can I just give this?' He said yes. He stared at me, he was in real shock.
"When he realised who I was his face just dropped. He was really, really shocked. He took the letter as he went up the stairs."
Lorna, a former model from Droylsden, Manchester, thought she had a breakthrough when Calum promised he would take a paternity test in 2009.
She travelled to a private London clinic for a DNA test arranged with his mum Angie -- but Calum failed to show up.
Lorna says she is homeless and broke after being forced to quit her home and move in with relatives in Co Cavan.
The struggling mum said she moved to Ireland to give Amelia a better life, along with her brother Connor.
Lorna says she does not want money from Calum. "At first I was bitter but I am nothing like that now."
A spokesperson for Calum refused to go into detail on the matter.
"As ever, when it comes to this woman, it's a private matter. At least it is for Calum. Obviously that's not the case as far as she is concerned."
