Lady Gaga is set to be the subject of a racy new adult film.

Hustler Video's 'This Ain't Lady Gaga XXX' features adult actress Helly Mae Hellfire as the pop superstar, performing sex acts with toys, girls and industry veteran Ron Jeremy.

It isn't the first time Hustler bosses have parodied a big star - Paris Hilton, Lindsay Lohan, Oprah Winfrey and Angelina Jolie have also been portrayed in saucy past films.

And the new DVD features the fake Gaga getting down and dirty with other celebrity doppelgangers.

Director Axel Braun tells WENN, "Let's just say that Gaga isn't the only sexy, female musician we have parodied in this movie. It's too hot to even describe. You just have to watch it."

The spoof also includes the parodied music video of Lady Gaga's hit song, "Telephone."
