Carey, 47, shared two photos of Bianca, and her very own hashtag, on Twitter, with the captions "Ladies and gentlemen... #Bianca" and "#Bianca returns."
The character – last seen romancing Jerry O'Connell and bathroom-brawling with Carey in the 1999 music video for her hit, "Heartbreaker" – has gotten a sultry style upgrade after her 17-year hiatus. She's swapped a red miniskirt and sweater for a black leotard, black leggings and black heels.
Not announced: When fans can expect to see Bianca appear onscreen.
Or, crazier question, might she appear in Carey's eight-part E! docuseries?
