Lady Gaga to deliver 'mind-blowing' performance at Oscars, promises song-writing partner Diane Warren

Lady Gaga’s song-writing partner has teased a “mind-blowing” performance from the singer at the Oscars.

The Born This Way singer will be performing ‘Til It Happens To You, her Oscar-nominated collaboration with Diane Warren from documentary The Hunting Ground, and Diane revealed even she does not know exactly what Lady Gaga has in store.

“Gaga delivers. Put her on a stage and she will blow you away. I can’t wait to see what she does, I know it’ll be mind-blowing,” Diane vowed.

The Hunting Ground explores the topic of rape on US college campuses and both Diane and Gaga have spoken out about their experiences with sexual assault since the song was released.

Diane revealed that recording the song had been uncomfortable for Gaga.

She told the Press Association: “She’s had her own experiences and it’s been difficult for her, but I think this is healing.

“I think she had reservations at first about putting herself out there, but once she starting playing, it was so inspired and epic and it became something so powerful that neither of us saw (coming).”
