Your cheeks are Roses, my love Soft and color Yours and mine Brush with ardor
(original in Spanish) Mejillas Coloridas
Tus mejillas son Rosas, mi amor Suaves y color Tuyas y mías Rozan con ardor
Originally written in Spanish. I know that it doesn't rhyme that much in English, but oh well. The Spanish version is structured in 5 lines, each with 3 words and 5 syllables.
