Speaking about the rumour, the 34-year-old Dublin actor said: “That’s the one time when you think it might be useful to have some sort of social-media thing to say, ‘This is b*******’,” he said.
“But then I thought, ‘Why do I have to engage and stoop to their level?’ This time it wasn’t that offensive and there’s a bit of fun in it because it’s so hilarious, but it could have been something more salacious.”
Reflecting on the downside of fame, he added: "There have been moments when you’re in the very early days of a relationship and a photographer comes out of nowhere. You’re walking in the park or you’re having a moment that’s quite private.
“I never want to be that person with sunglasses down, looking around before they leave the building.
“I’ve felt pretty bad in the past when photos have been printed. I can deal with it, but it’s not fair on the other person. It’s about responsibility.”
