In A Star Is Born, Gaga plays an emerging pop star married to Bradley Cooper’s ageing rocker who is battling drink and drug addictions.

And Gaga, real name Stefani Germanotta, dedicated the film to people battling addiction.

She said: “I wanted nothing more to show the truth and power of this very heartbreaking dynamic. The true star of the film is not me; it is bravery and it is perseverance.”

The actress and pop star also thanked first-time director Cooper for being a “magical filmmaker” and a “magical human being”.

She said: “I have never had an experience with a director or an actor like I had with you and I will cherish it forever. You seamlessly were both the love of my life and the man behind the camera.”

Close, 71, repeated her success from the Golden Globes, where she was also named best actress.

The veteran performer paid tribute to her fellow nominees; Olivia Colman, Emily Blunt, Toni Collette,  Melissa McCarthy and Yalitza Aparicio.

She said: “I think I can speak for all of the women in this room: We celebrate each other, and we are proud to be in this room together.”

Gaga also took home the best original song prize for Shallow, the hit track from A Star Is Born.

Earlier in the evening at the star-studded ceremony held at Santa Monica’s Barker Hangar, Amy Adams and Patricia Arquette shared the best actress in a limited series or movie made for television award.

Adams was recognised for Sharp Objects while Arquette won for Escape At Dannemora.
