I attempted to do a very quick translation since it was the first time that I have seen it as well, and because I couldn't understand some parts of it, it's obviously not the greatest. Oh well...
...
D: There are many people! It's impressive!
D: How does it make you feel that you are going to hear Alizée for the first time in your life (couldn’t quite make out what he was saying)?
Little Girl: That makes us feel something because we have never seen her, it’s the first time she has done a tour.
D: Go on, come with me!
D: Do you realize? I have Alizeé in front of me!
D: "L’Olympia" it’s a big step (for you) because I believe that you have never done such a large show. How does that make you feel?
A: The first night I had a lot of _____ because I made it to the stage of Olympia because that’s where all the big stars are made, and before it was recognition (that I received?), and I tell myself that I am very lucky to go there this time. (This part is kind of screwed up, lol)
D: Alizée, I know that there are many people of my age who would like to become singers. What advice could you give them?
A: To believe in their dream and have the willpower to do it, to never abandon it, and especially to always remain natural and not try to be another person
D: Do you like Alizée’s voice or her physique (or something like that, I can’t hear him over the music)?
Guy: Her physique.
D: Oh wow, you are honest!
D: We have seen you often dressed in miniskirts, very sexy, is it to attract the attention of the boys?
A: Very simply, because I like skirts, and I tell myself that if I don’t wear them now, I will never wear them.
D: How was it?
Little Girl: Great!
D: And you, did you like it?
Guy: It was very, very.... (don't know what he's saying at the end).
Little Girl: No, it was super!
Teenage Girl: I touched her hand, so I am very happy!
D: Alizée..... (couldn't make this one out either)
Guy: Yes...... (don't know what he says after that)
D: Thank you very much (from the class?), ciao!
