Mariah Carey, who suffocated that dog moments after this photo was taken, has apparently never heard Hollywood Rule #4,080: Ugly roles get awards.

Unlike past Oscar winners Nicole Kidman, who wore a large prosthetic nose in The Hours, and Charlize Theron, who transformed herself into a truck stop whore for Monster, Carey decided to forgo changing her appearance for her role in the upcoming film Tennessee.

Carey plays a Southern waitress who sets off with two brothers in search of their father. While she consented to cornrows, she passed on the fake nose and bushy eyebrows that had been conceived for the part.

"When she saw the nose, she called her people and decided against it," says the source. "She was not a diva about it, but she did seem very insecure about her appearance."

Ironically, now that Mariah Carey has refused to look ugly on the outside, we can all be certain that she's hideous on the inside.
