Hello Mariah Cannon? Is Mariah Carey changing her name to Mariah Cannon?

Today chatter is claiming that Carey has changed her name legally to Cannon and is asking staffers to call her Mrs. Cannon. But how about her professional name?

MTO claims that Carey has told staffers that they have one week to learn the new Mrs. Cannon and refer to her as such. But no indication if there would be a professional name change for Carey to Cannon.

Celebrities often opt for different legal names at home versus stage names after marraige. Recently, Ashlee Simpson announced she would go by Ashlee Wentz but professionally by Ashlee Simpson-Wentz. In contrast, Ivana Trump still goes by Ivana Trump despite being divorced from Donald Trump and remarried to someone else.

No confirmation from Carey.
