Depends if you mean : How cute !!!! it is "Qu'il est mignon ! " (if you're talking about a guy) or "Qu'elle est mignonne (if you're talking about a girl) or Qu'est-ce qu'il (elle) est mignon (nne) !!!! If it is in a question example : How cute is Crisdean ? The way I would translate it "A quel point Crisdean est-il mignon ? "
