Did she really get facial surgery or not?
People say she did but she denies it hence her sudden change in look. The more I see her now the more I am adjusted to her recent look and it looks more and more similar to her old look but just aged fast. I think the weird confusion comes from the fact that she can look Asian (slant eyes) and open eyes (normal for her race in a sense). She gave many hard on's back in the Me, Myself, and Irene era.

2014 was the changer that got everyone confused.
