Looks like Ske Leton got a couple of autographs at tonights show in Nice. He'll probably be posting some more pictures and videos tomorrow or maybe even later tonight. There's some info on this guy in his FB profile. He lives down the coast away from Nice, about halfway between Marseille and Nice. He attended college in Paris. He speaks 4 different languages. Not much else except it looks like he apparently discovered Alizée ' la chanteuse' in 2013.
EDIT: I sent Ske Leton a short message and he said he didn't know her before 2013 and said it was the first time in his life he cared to follow a celebrity.
Virginie Nini also posted the bottom picture. What a great smile on Alizée's face! Nini is from Toulouse.
