Their contact came while Bono was working on ‘The Mirror Maker (Rosalía)’, the fourth track on U2’s forthcoming album ‘Carnaval De Luz’ .

“I don’t know him personally, but he texted me and told me that he had this new project and this song, ‘The Mirror Maker’,” Rosalía told Fallon.

She said Bono then asked whether some of the Spanish words he had written actually made sense.

Rosalía recalled being puzzled by one in particular, saying she had “never heard this word” and eventually researched it to discover that it did not exist in standard Spanish.

Her advice to Bono was straightforward: “I don’t know, but feel free to invent your own language.” She went on to describe the entire situation as “mind-blowing”, adding that she had grown up listening to U2 and singing a snippet of ‘With Or Without You’.

“Bono is a legend,” she said.

“It’s incredible.” Bono first revealed the story behind ‘The Mirror Maker (Rosalía)’ last month , describing the singer as an “extraordinary artist”.

“We normally just write songs about people in jail or dead people,” he joked at the time.

“This is just celebrating somebody just because they’re an extraordinary artist.” He said he had become particularly fascinated by Rosalía’s 2025 album ‘Lux’ , with its themes of spirituality and “re-enchantment” overlapping with some of the ideas U2 had been exploring on ‘Carnaval De Luz’.

“She’s arrived at the same point just before us, which is annoying and also really inspiring,” Bono said.

The song itself actually began life around 2017 as a demo by The Edge titled ‘Kuti Rocker’, inspired by Fela Kuti .

Producer Jacknife Lee has said the version eventually selected for the album was its 196th iteration.
