The actor and the former Ireland rugby captain have been married since 2010, but Amy revealed that the couple first locked lips on a night out in Dublin back in 2005.
Speaking to Doireann Garrihy on The Laughs of Your Life podcast, the 43-year-old said that she and Brian had been exchanging texts for a while before sharing their first “shift” in Café en Seine.
The mother-of-three explained: “We met in.... I think I was 26 when I met him. I first shifted him downstairs [in Cafe en Seine]. It was a historic moment.
“It was [at the] bar. You know when you're just too giddy. I’d had way too much. You know when it's been in the air and there'd been loads of texting.”
Brian and Amy tied the knot in July 2010 at Lough Rynn Castle in Co. Leitrim. They now share three children together: daughter Sadie and sons Billy and Ted.
But the Finding Joy star’s dating life hasn’t always gone so smoothly, as she spoke of how she moved to London to be with a previous boyfriend only to be dumped by him shortly afterwards.
“I lived in London over the years a lot in my twenties,” she began.
“I was going out with this guy and I was delighted with life. I got a new flat for myself.
“We were in the highs of romance and he said, ‘You should find a flat near me.’ I was like, ‘I will do that.’
Amy continued: “I was mad about this guy and I was so excited. It was back in the day, you’d swear it was the 1800s, but I shipped my stuff off to England.
“A van came, I got no receipt, and I was like, ‘I don’t know if I’ll ever see those again.’
“I was moving into this flat with a mate of mine. I felt like a real grownup, dating this hot guy, got my new flat in London.
“The night before I was going back over, he decided that was not in the plan for him. It wasn’t ideal.”
She added that she also lived very close to her ex and feared bumping into him announced.
“I had to wear black tie every time I went to get milk because I thought he could be anywhere, I have to look my best at all times,” she laughed.
