Bride-to be Rosanna Davison has joked that she is worried her big day will be hijacked by TV lout Damo.
The top model fears that Andy Quirke's alter ego will arrive at her wedding with a bag full of Dutch Gold.
Comedian Andy is best man to former Miss World Rosanna's husband-to-be Wesley Quirke.
"We will have Damo on the top table so can you imagine what the best man speech will be like?" Rosanna told The Diary.
"With Andy doing Damo, I can only imagine what he might say. He knows all of Wes's secrets."
Luciky, their guests will also include the extended Quirke and Davison families, who already familiar with Andy's hit RTE series.
But Rosanna has more to worry about than theur future brother-in-law-she is kept busy planning the marriage every day.
"It's constant and a bit stressful," Rosanna said.
"Working between Dublin, London and Germany, I find planes are a good place to write to-do lists. It's the only way I can get on top of things."
But the Diary can exclusively reveal that the model has one major obstacle behind her -- finding a wedding dress.
"I've got the perfect one," she said. "My mum has seen it too and we're both very happy with it. I better not say where it's from in case word gets out."
Another thing Rosanna may be able to cross off her list is a singer, with dad Chris de Burgh having clocked up sales of 45m records during his career.
"I'd love dad to sing, but at the same time I want him to feel he can enjoy the day without having the pressure of a gig and having to entertain people," Rosanna said. "We have to see what the mood is like and not put pressure on him."
With part of the wedding in Ireland and the rest abroad, those attending will be keeping an eye on their letterbox in March when the invitations go out.
