She has apparently had surgery, but she looks like a different person.
The only thing that makes me think the new photo is of her is that the lips have the same shape. Otherwise, it could be a totally different person. I'm not questioning her desire to have surgery, and she still looks fantastic, but what is going on here? Is it an unknown sister, or a hoax?
She's lost a lotta weight, gained some age and had her eyelids done. wouldn't you if someone was always poking a camera in your face and commenting on your wrinkles on websites?
