Hozier recounts meeting Cillian Murphy that inspired the lyrics to “Too Sweet.”

Hozier recounts the time he met Oscar-winning actress Cillian Murphy while suffering from a really bad hangover.

Hozier recalled the story during a concert at the Xcel Energy Center in Saint Paul.

She told fans she met a best friend the night before she fell for Murphy and ended up “drinking heavily all night, just like you.”

The musician had a flight to catch the next morning and arrived at the airport nursing a hangover.

Recounting the morning after the drink, he said: “I get up quickly and I’m quite tall. I’ve been told, “If I fall down, I’d be halfway home”… I was walking full speed ahead and I just went, “Boom!” My head hit the window so hard.”

He recalled walking “straight into a wall” but managed to make it to the airport.

“I’m like rattled. You know, the kind of hangover that makes you shake,” he continued.

He added: “And then I look to my left on this plane and I see a famous Irish actor. I’m also subject to celebrity shock when you see someone you’ve seen on screen a thousand times and you’re like, “Oh my god, that’s a famous person.” And when I see Cillian Murphy is on my left…”

The actor recognized Hozier and approached him to greet him. At the same time the Too sweet the hitmaker touched his head and realized his head was bleeding.

“I’m like, ‘Oh my god, that’s wet.’ So I’m on the plane and I’m looking at my fingers, like I’m bleeding a little. And I turn to my left and Cillian Murphy is sulking next to my seat and he’s like, “How’s it going?” I try to play it cool. He was so sweet and so kind.”

Hozier revealed that meeting Cillian Murphy inspired a line in his hit song Too sweet.

“It’s the line, ‘I aim low, I aim true, and the ground is where I’m going.’ I’ve never told Cillian Murphy, I haven’t seen him since. I didn’t have the guts to tell him at the time what shape I was in,” she shared.
