Lady Gaga will make her debut as a runway model at Paris Fashion Week later today (March 2).

The singer will appear during Thierry Mugler's show to premiere new song, 'Government Hooker'.

In a message on Twitter, Lady Gaga said she had directed the music for the show and was “so excited I might give birth to a machine gun”.

In January, the singer debuted another new song called 'Scheiße' during one of Mugler's shows.

Both tracks are taken from Lady Gaga's forthcoming album 'Born This Way', which is due to be released in May.

Mugler's creative director Nicola Formichetti is close friend and Lady Gaga's personal stylist.
