(CBS) Lady Gaga premiered a new song while making her runway debut during Thierry Mugler women's fall 2011 fashion show in Paris Wednesday.

While smoking a cigarette, the pop star first hit the catwalk in a sheer black top and pencil skirt with long piggy tales as her new track, "Government Hooker," off her forthcoming album "Born this Way," blasted in the background.

She later closed the show, which also featured her other songs "Born This Way" and "ScheiBe," sashaying in an all white gown with sky-high platforms.

The collection, presented in a gym in eastern Paris, was designed by Gaga's stylist and Mugler creative director Nicola Formichetti. It was Formichetti's first womenswear show under the label.
