Well let's see.
The idea is to think of one word or a short "pair of words" for one target group at a time, but since we're talking about Alizée, that's hardly enough...
There can be several target groups; such as: Family, friends, acquaintances, best friend, female friend, male friend, wife, husband, etc.
I’ll write a few words at first, but it would be nice to try to find together the best “standard words” that could make Alizée more familiar to others(, who do not yet know her -) because basically you can say so many adjectives about her!

So by discussing words and adjectives, every time we come up with new ones, we also find the best and most appropriate words / sayings / "phrases" etc!

A couple of starts: 
For the family: Warm hearted, friendly, lovely, beautiful
Male friend: Damn sexy
Female friend: Very good looking
Wife / Husband: Excellent singing voice
