The two will shoot scenes depicting a Country Western music concert Tuesday and Wednesday.
In addition to a thrilling headline performance Saturday night, Lady Gaga is preparing to shoot portions of the A Star Is Born reboot at Coachella this week along with director and co-star Bradley Cooper.
The official Coachella app featured the invitation, which said that Gaga is slated to film scenes for the film at Empire Polo Club, the same location in Indio, Calif., where Coachella takes place.
Cooper is making his directorial debut in the Warner Bros. remake of the film, which chronicles the story of an up-and-coming starlet who struggles to break into the entertainment world with guidance from an industry veteran on the way down. The Oscar-winning actor will join Gaga onstage Tuesday and Wednesday to film some scenes that take place during a country concert.
The solicitation for extras invites Little Monsters to “be in the audience as Bradley Cooper and Lady Gaga films scenes on the actual Coachella stages. Help cheer and applaud their performances on camera…the scenes for these days will portray 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!” Tickets for the special event are $10 (attendees must be 18+), with all proceeds going to Gaga’s nonprofit, Born This Way Foundation.
The invite — which noted that attendees’ phones will be locked in a Yondr pouch to avoid leaked footage — came Sunday morning, just hours after Gaga played to a massive crowd in a headlining slot originally held by Beyonce, who had to beg off due to her pregnancy. In addition to playing a string of hits, Gaga debuted the new track “The Cure” during the 90-minute set.
