The 'Born This Way' singer gave her best strut down the catwalk at the Thierry Mugler show, which also featured her latest single, from her Born This Way album, 'Government Hooker'.
Speaking ahead of the show, Gaga tweeted: "so excited I might give birth to a machine gun. (sic)"
It was recently claimed Gaga is set to take on a bigger role at the French fashion house.
"I directed the show music" and will be previewing "Government Hooker," Gaga added.
Stylist and creative director of the brand Nicola Formichetti hinted more work could be in the pipeline between the two following her role as musical-director of the menswear show.He said: "I want people to think, 'Ok, there's something new happening.' I want people to get excited again, not only fashion people.
Talking about a future collaboration, he added: "It's me and her just having fun and getting very inspired from the idea of Mugler. She's very much involved, more in the early stages."
Speaking about the track that will be used in the show, Formichetti - who was the designer responsible for the infamous meat dress worn by the 'Alejandro' singer - has said: "It's very, very hard, but pop at the same time. It's really amazing.
"When I heard it, I said, 'That's Mugler.' She's remixing it especially for the show."
