The "Super Bass" rapper stepped out on Christmas Day evening in the black, tight-fitting outfit, reports dailymail.co.uk.
Minaj, 30, was the guest of honour as she was attending her own festive party, held here.
She made sure that she was centre of attention by wearing the extremely low-cut black ensemble. She was fairly close to having a wardrobe malfunction, but she escaped the embarrassment.
Minaj, who was sporting a sleek bob hairdo, teamed the catsuit with a thick black belt and a large pair of red and black sunglasses.
