The Nadine is a stage prop, designed to be a green Rolls Royce, which contains a keyboard under the hood that Lady Gaga used during The Monster Ball Tour. The green rusted car is present during the performances of "Glitter and Grease" and "Just Dance". During the concert, the car is seen going on it's way to The Monster Ball Tour, but breaks down and Gaga starts to perform "Glitter and Grease".
The inspiration for Nadine came from a real Chevrolet El Camino owned by Lüc Carl. The original car was watermelon-green and inspired "Glitter and Grease".
It was originally intended to be in the music video for "Telephone", but was replaced with the Pussy Wagon from Kill Bill.
