Scruffy, you are probably correct in your post. Good detective work!
I am one to believe that the split from MF/LB caused a rift between Alizee and Mylene, despite what we were led to believe. I'm glad to see that all seems to be well between the two now.
If this was Mylene's way of saying thank you, that is one heck of a thank you! It helps solidify Alizee's legacy as a performer and keeps her music relevant even today.
