article where Alizée was asked if she had heard that Jenifer is releasing a France Gall cover album [pages 6-7], and there was a bitter tone in her responses. She said things like "Has Jenifer ever talked about France Gall? ....someone should ask Jenifer if she has listened to France Gall since she was born..."
From listening to the radio interview she did for MFM, she just said that it wasn't her thing to make entire cover albums, she wasn't jealous or had a problem with Jenifer, but doing cover albums of artists who are still here, still alive, bothers her a little bit, but that Patricia Kaas doing a cover album of Édith Piaf bothered her less (I'm assuming because Piaf passed a long time ago).
So yea she certainly isn't excited about Jenifer doing this album, from what I can tell.
