someone like Whitney Houston is an example of a performer who was put on the highest pedestal that our culture provides. she was a genuine internationally beloved superstar DIVA. and so her fall from grace was most tragic and dramatic. perhaps she's turned her life around now - but until she comes back reminding everyone of why we fell SO deeply in love with her (ie: glamourous, elegant, that VOICE), she'll never end her story as the LEGENDARY icon that she should be.
sorry for the odd comparison as i know Lindsay isn't on that level. lol. but i just think she's gotta hit the qualities that we loved about her in order to have a proper and successful comeback.
