Oh, Mariah Carey. Don’t ever change. The eccentric diva threw an “intimate” party at her rented villa in Italy recently at which attendees were expected to abide by a very, very strict dress code: dress up as Mariah Carey. Both male and female attendees, even. Yup, Carey insisted on a whole room full of tributes to her various looks, and if anyone can pull off such a demand, it’s her. RELATED: Anonymous source calls Liam Hemsworth a liar But Carey herself, never one to risk coming in second in a costume contest — even if she is in fact the real article — did not go as herself. Instead, she reintroduced her black-clad, stiletto-heeled alter ego, Bianca. Because of course she did. Again, ma’am, please don’t ever change. Follow Ned Ehrbar on Twitter @nedrick
