I just found this on the net:

Chris is singing with ANAIS the song Si j'avais su que notre amour! Has anybody heard this song before.

I listened to the song, but I would have never thought even for one second that this is Chris. This voice sounds absolutely strange?

I wonder what you think about!

Greetings from Austria!

Hi, you are right. It does sound really strange.

Perhaps it's not really Chris but a clone! It certainly doesn't sound like him.

Yeah, she's a french singer and it's a "duo rêvé" (dreamed duet) which means, she asked for Chris (to his management I suppose..) but since she got a negative answer, she had this pale imitation instead.

Thanks Claire for interpreting! And as my french is not so good, I thought that her dream became true as dream duet, so I was a little confused, because the voice doesn't nearly sound like Chris.

Bye!
