Did Fergie have a noselift?

I find Fergie very hot but on the back of my head, whenever I look at her, something is wrong.I am trying to figure out what is wrong with her face. Then when I was with friends, I raised that to them and their eyes all rolled and told me "what do you think"? So I was still left unanswered and they just smiled then laughed and I think they were probably thinking that it was not my business anymore. She's rich, famous and she has it all.
