Lady Gaga rocks the Thierry Mugler runway

Lady Gaga made her catwalk debut in suitably scene-stealing style last night, rocking the Paris Fashion Week runway for the Thierry Mugler autumn/winter 2011 collection.

Out to support her superstar-stylist, Nicola Formichetti, in his first show as Mugler's creative director, the Lady donned long blonde pigtails and a sheer black dress with latex skirt to take her first strides before the world's style pack, puffing on a cigarette to a soundtrack of new own music - a previously unheard track, Government Hooker.

Switching to a second look, she transformed into Formichetti's unconventional bride in a corseted long white gown and nine-inch heels to accompany the designer as he faced his audience, working it to her latest single, Born this Way.

The songstress revealed her excitement pre-show via her Twitter
