The 26-year-old actress took to Twitter to post her picture along with the celebrated musician with the Eiffel Tower in the backdrop.
"What a privilege to have worked with the genius that is Alan Menken @beourguest #aladdin #pocahontas #thelittlemermaid," Emma wrote.
Menken has won two Academy Awards each for his scores in Disney films such as "The Little Mermaid", "Aladdin", "Pocahontas" and the 1991 version of "Beauty and the Beast".
Emma was in Paris for a photo call for her upcoming movie, along with co-stars Dan Stevens and Luke Evans.
