Yesterday Lady Gaga premiered her new song "Government Hooker" at the Thierry Mugler fashion show in Paris, and the pop star also walked the runway in a pair of monstrous platforms and a floor length white gown. When the show wrapped, Gaga free-boobed it and slipped into a see through catsuit, and later we photographed her arriving at Maxime Bar carrying a glass of champagne.

Apparently you're allowed to drink in the streets of France, but given the height of the shoes she's wearing, it might have made more sense for her pal to be carrying the bubbly -- thankfully she didn't trip!
