Well, Mariah withdrew her application to trademark "Queen of Christmas" because of the opposition she received. So, legally anyone can use it. I'm glad Sherri said "self-proclaimed." It was ridiculous for Mariah to even attempt to make the title official. Did Aretha, Mary J., or even Michael Jackson ever attempt to legalize their royal titles? No, they allowed the public to just widely recognize it. Mariah should have done the same, but instead she turned it into a debatable issue.
