English songs?

[Taralia]

Me and a friend of mine are discussing wether Ayumi has recorded any english songs or not. I'm saying that she never has but my friend says that you can never be sure of that. He's saying that she maybe has recorded a english song for fun before she became famous. I know that she sang Silent Night with Gackt but that is not what my friend means because that song was never recorded and realesed as a single.

So what do you guys say? Is it possible tha Ayumi may have recorded a song in english?

(Sorry for my english)
