Personal Note: Have always known that Yoyo speaks weirdly, but did not think of it as a lisp.
Funny that Yoyo said that she cannot do stage performances because the tone that she hears does now match what she sings. :P
Yoyo doesn't film ancient series because a producer once told her that her eyebrows are too thick, and she doesn't really want to make them thinner. (I have always loved Yoyo's eyebrows!)
