Dave... what have you done ? How dare you?
In all seriousness, the host of the show (Laurent Ruquier) is very good at promoting his guests ... that's why he said he fell in love with her album at first hearing .. but he then asked Dave's opinion and he started by saying that she looked much better in real life than on her album cover ( in a kinda sarcastic way) and also implied that Alizée didn't age well from what he remembered of mylène's Lolita before trying to correct himself feeling the awkward silence that ensued. And there comes the insulting part, he said the she looked like a "pétasse" ( bitch/slut ) on the album cover.
Well, well ... I will now take my leave and get my battle axe sharpened and ready ...
