Lady GaGa will make her debut as a runway model at Paris Fashion Week tonight (02.03.11).

The 'Born This Way' singer will strut down the catwalk at the Thierry Mugler show, which will also feature a new song by her, '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.

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."
