Here is a good profile shot of Alizee when she was around 23.
I don't know why she would want to mess with perfection and I don't think she did. There might be some perceived differences based upon lighting and the angle at which the photo was taken. Age makes a difference. This thread has profile photos when Alizee was in her teens, 20's and 30's. If Alizee had a nose job along the way, we should be able to see it right off and I just can't see it.
