Oscar winner Russell Crowe continued his love affair with Ireland on Friday's Late Late Show, and said he is keen to find out more about his Irish roots. 

The Gladiator and A Beautiful Mind star is in Dublin ahead of a show by his band The Indoor Garden Party at Dublin's Olympia Theatre next month, and made good on his promise to host Ryan Tubridy that he would return to the Late Late couch.

"I've been here a number of times over the years," recounted Crowe. "But the last time I had a social event here was 2003. Since then, it's been hotel rooms, interview rooms, movie theatres, back on the plane.

"And yesterday - and I'm not taking the p***, just factual - was my first sunny day in Dublin out of all the times that I've visited. So that was a great experience! And today, actually, I went for a walk. It felt like, 'Woo-hoo!'"

Presuming he was about to be asked about his favourite pub, Crowe continued: "I was thinking about that. Why would I shrink my opportunities? I don't think it's possible for me to say I've been in to a pub in Dublin where I got a s*** pint. It's just not possible."

"Why pick one pub, when I'll just go to all of them over time?" Crowe asked. "Make new friends."  

As souvenirs of his visit to the Late Late, Munster supporter Crowe was given a Munster jersey with his name on the back and a box of Barry's Tea, rebranded Russell's Tea, for the occasion. 

Crowe was later asked if he had any Irish blood, because there is a Crowe convention taking place in Thurles, Co Tipperary in October. 

"We know that there is an Irish connection," the actor replied. "But it's actually... we haven't been able to track it down. We've got Welsh on my dad's side and Scottish on my mum's side and a few other things too - Italian, Norwegian, Maori. It's a bit of a combination of things, yeah."

"We're just going to go Irish with this one," said Tubridy. "We're going to claim you." 

"I should've just said 'Yes'," replied Crowe, before taking to the stage to perform with his band.
