Lady Gaga is calling on her fans to be a part of her new film with Bradley Cooper, A Star is Born.

The superstar musician tweeted out an invite to all her Little Monsters on Wednesday (April 26) to attend a filming event at the Greek Theatre in Los Angeles on May 2 and 3. According to a posting on the Greek website, tickets are $12 per day to be a member of the audience in a scene portraying a country western music concert.

"All you Monsters that can attend should get decked out in your most comfortable denim & boots, throw on a Stetson (leave those pink Joanne hats at home) and come out to show your support," the website states.

Ticket proceeds go to Gaga's Born This Way Foundation. Attendees must be 18 years or older.

Cell phones and cameras are not permitted during the filming and will be secured in Yondr pouches to prevent the devices' use.
