The 19-year-old Skyscraper singer confessed that she has to use a teleprompter when performing a song in the language.
Appearing on Late Night with Jimmy Fallon, she said, 'I've memorised songs in Spanish before.
'I had a song called Lo Que Soy which is This Is Me in Spanish. I decided to sing the song half [in] English, half [in] Spanish. But my brain like would not memorise it, the day before, I was like I might need a teleprompter!
'While I'm gliding through fog in a tight, red dress, I'm reading a teleprompter, trying to look graceful just praying to God that I don't fall in my dress.'
