Swept up in the ‘Kiss me, I’m Irish,’ craze around St. Patrick’s Day, the women in the bar start asking Jason for a peck – one of them played by his mother.

Now, in a sweet new interview with People, Jason shared that Coni was ‘terrified’ of forgetting his lines and he had to reassure her the script was just ‘a guideline.’

Jason Momoa warmly revealed that his mother Coni was ‘terrified’ to act with him in the rollicking new Guinness ad he directed

He spent ‘a decade’ contacting Guinness about the possibility of an ad, and when the project finally materialized he insisted on Coni’s involvement.

Jason’s reasons were sentimental, a ‘she’s the one that introduced Guinness to me. It only made sense for us to be together.’

He recalled how scared she was to go up on her dialogue, saying: ‘She did a great job, but it was really cute to see my mom kind of panicked on the lines.’

To allay her anxiety, he pointed out that the team on his upcoming Minecraft movie constantly ‘change lines’ over the course of the shoot.

‘I’m like: “See, Mom, it’s a guideline. The script is a guideline, too. You’re playing a character. It’s okay, Mom, we’re just going to do this.” She’s just so nervous,’ said he.

As for his proportion of Irish ancestry, Jason theorized that he had ‘probably a little more’ than the 2% used as a joke in the commercial.

‘My mom’s German and she’s got Irish, but it’s predominantly German. But yeah, Grandma definitely had Irish in there, so my mom did all the stuff.’

Coni celebrates St. Patrick’s Day, but the occasion is ‘another day for my mom,’ the Game Of Thrones beefcake spilled. ‘We’re drinking Guinness.’

In a sequence shot like an action movie chase scene, Jason bursts into a bar and proudly announces that he is ‘Irish’ – in spite of that being just 2% of his DNA

In a short YouTube documentary for Carhartt Handmade Films a few years ago, Jason spoke glowingly about the upbringing his mother gave him.

‘I was raised by a strong single mother. My mom’s an artist in every way. She’s a painter, a photographer,’ the Aquaman star said.

‘She’s a wanderer, always searching, always seeing. I guess you could say my mom gave me her eyes,’ Jason remembered fondly.

My mom introduced me to skateboarding and rock-climbing, and I absolutely love her for that, because skateboarding – it gave birth to a style for me. It wasn’t just the skating. It was the music, it was the crew, the underground,’

Rock-climbing, meanwhile, ‘made me fix my fears and my doubts, explore the impossibles, problem-solve through movement.’
