Is Mariah Carey going through a new transformation? That's what her fans can't help but wonder as the chart topper has revealed a brand new look on Instagram - shocking her millions of fans from around the world.

Wearing a black wig, cat suit and thigh-high boots, Mariah revealed that her alter ego Bianca - from her hit music video "Heartbreaker" almost 17 years ago - is back and apparently, here to stay.

Mariah captioned her photo simply with, "Ladies and gentlemen... Bianca." And while the new look is a hit with a lot of her fans, some can't help but call it both "bizarre" and "strange" for her to be playing dress up again.

Many comments from followers included, "As one of your big fans for a very long time I will say that I like and miss the old you," along with, "OMG she looks so much like Janet Jackson here. I feel like there's a new video in the works!"

Another fan wrote, "Mariah you don't need to do this. No judgment to pass but you have the beauty and compassion to sing and it comes from the inner depth of you. You don't need to do stuff like this to get attention, use your talent instead."

So far Mariah herself hasn't specified why Bianca is back or if she plans on using her alter-ego in an upcoming video or project.
