Lady Gaga and her former co-star Bradley Cooper reunited at the premiere of his new biopic Maestro in Los Angeles on Tuesday, which was also attended by his new leading lady Carey Mulligan and his daughter Lea. 

Gaga, 37, who starred opposite Bradley in 2018 musical A Star Is Born, went shirtless under a chic black blazer with silver embellishments, and fitted black pants as she supported Bradley, 48, at the event, held at the Academy Museum.

Mulligan, 38, brought the glamour in an off-shoulder floor-length glitzy navy gown with dramatic sleeves. The English actress wore her platinum blonde bob in a short straight style for the occasion.

Maya Hawke, 25, was also in attendance, and rocked a structured ballerina-style brown and white sleeveless dress, which she paired with white stockings and pink heels.

Cooper and Mulligan’s new film Maestro follows the longtime relationship between conductor-composer Leonard Bernstein (Cooper) and actress Felicia Montealegre Cohn Bernstein (Mulligan).

Gaga and Bradley collaborated on A Star Is Born five years prior, which starred him as a hard-drinking musician who discovers and falls in love with a singer, played by Gaga.

The film received eight Oscar nominations, including Best Actor for Cooper and Best Actress for Gaga.

The blonde bombshell happily accompanied Cooper and his mini-me into the auditorium for a screening of the film.

Bradley looked every inch the proud father as he held hands with his six-year-old daughter — whom he shares with ex-girlfriend Russian supermodel Irina Shayk, 37 — during her red carpet debut.

While he opted for a classic three-piece navy suit for the occasion, Lea wore a cheetah-print Dolce & Gabbana dress, white ballet flats as well as a red and black crossbody purse.

Lea also made her acting debut in the film, where she plays the younger version of Leonard and Felicia’s daughter Jamie Bernstein, who is later portrayed by Maya in the film.

Maya — who’s the daughter of Hollywood legends Ethan Hawke and Uma Thurman in reality — styled her tresses in a shaggy mullet, and opted for black eyeliner and dark red lipstick.

Bradley and Carey appeared in good spirits as they both smiled while posing alongside each other on the red carpet.
