Could Marie Antoinette speak French?

She learned Italian, from Metastasio, on top of the necessary French and German, as well as Austrian history and French history, though from an Austrian perspective. But while she flourished in her learnings of Italian, her other languages proved to be a weak point. Conversations with her were stilted, and her ability to read and write German and French (the 'universal' language of Europe at this point in time) was undeniably poor.
