Rosalía says Bono reached out to her for Spanish advice while U2 prepares the album *Carnaval de Luz*, which includes a song about her titled “The Mirror Maker (Rosalía).” Speaking on *The Tonight Show Starring Jimmy Fallon*, Rosalía explains that she had trouble understanding one of Bono’s lyrics and that she discussed the wording with him.
According to Rosalía, Bono told her to “feel free to invent your own language,” framing the lyric as something creative rather than strictly literal. Outlets also describe the exchange as Bono seeking her perspective on Spanish language use for the tribute song. While coverage differs in emphasis—some focus on the anecdote itself and others on the quote—the accounts are consistent that Bono consulted Rosalía on Spanish for the track, and that the resulting approach allows for invented or playful language within the song.
