The 43-year-old mother of twins is shooting a music video in Italy with Miguel for their R&B hit, "#Beautiful."
She posted the picture on her Twitter with the caption, "Behind the scenes on set with @MiguelUnlimited!! coming soon:)"
In the pic, Carey kept her sandy blonde locks loose and wavy as she proudly flaunts her toned figure in a black one-piece with many strategic cut-outs.
The superstar diva — who had been busy judging hopefuls on “American Idol” — announced her much-anticipated return to music last month.
