The UCD graduate weds long time boyfriend Wesley Quirke – the pair have been dating since 2006.
“I will be wearing the waterproof eyeliner and mascara and tissues! It’s very much a landmark in your life”, she told VIP Magazine.
She might not be the only one in need of it however - she thinks Dad Chris de Burgh may shed a tear.
"My dad's a bit of an emotional type, so I think so!"
The former ‘Playboy’ cover girl also spoke of how the media interest in her wedding isn’t concerning her – she just wants it to be a memorable day for her family and friends.
“Wes and I really want our wedding day to be special for us and our family and friends
“Having invested so much time and energy into the relationship and planning the day, it will be emotional”.
However although she says she’s in no rush to start a family after the wedding – she definitely wants children further down the line.
“We definitely want kids as part of our future, but it would also be nice to spend some time as a married couple together and travel a bit more.”
