The journalist is due to walk down the aisle with Gerry Scollan -- the father to her four-month-old son, Patrick.
But far from serenading her over a candlelit dinner, her beau went down on bended knee while engaged in domestic chores.
"I should make up a really romantic story," she said.
"He was loading the dishwasher and said, 'Will we get married so?'
"And I said to him, 'Are you proposing?' He said yes. And I said, Yes I will!' And that was it."
She met her fiancé during a night out in O'Donoghue's pub on Merrion Row, where the smitten IT consultant asked for her phone number.
They first went public on their romance at the Peter Mark VIP Style Awards and were engaged a year later.
The Prime Time host admitted to the RTE Guide how she had almost accepted that becoming a mum wasn't on the card for hers.
"At 36, I just thought, 'Look, it's not going to happen and that's fine.' And then things changed pretty dramatically," she continued.
Now the devoted mum is looking forward to making things official some time this year.
"We'll do it at some stage, possibly by the end of the year. I'm just not sure when. It will be a small celebration with just family and close friends," she said.
"We're both of the same view and when you have a baby, it makes the huge fancy celebrations less important. The important thing is that you're going to get married."
The pair named their baby after Claire's late uncle Patrick, and Gerry's grandfather.
However, she was convinced that she was having a dark-haired girl and got a shock when a boy arrived.
"This boy arrives with hair that might be strawberry cloned and we're in the delivery room looking at him, wondering 'Who is this person?' So Patrick was a reserve name but it works really well," she added.
She made a well-publicised return to work just 10 weeks after having her baby and now works on two shows with RTE Radio 1 as well as flagship current affairs show Prime Time.
She is adamant she has no designs on eventually hosting something like the Late Late Show: "Everyone assumes it's an ambition but it's not an ambition for me.
"People always ask me what my dream job is and I still don't know. I'm doing a job that I really enjoy right now and I love the variety. What do I want to do next? I don't know."
