Lady Gaga's Coachella tribute to cancer-stricken friend

Pop star Lady Gaga paid tribute to her friend, who is battling cancer, during her set at Coachella over the weekend.

The 31-year-old singer headlined the annual music and arts festival in Indio, California, on Saturday for the second weekend in a row and during her performance she dedicated an acoustic version of "Edge of Glory" to her friend Sonja Durham, who is battling stage IV cancer, reported E! online.

"My friend Sonja is very sick and I love her so much and if it's okay with you, I'd like to sing this song for her. I'm sorry you don't feel well. We all wish you were here with us," Gag says.

Sonja used to work as Gaga's assistant and the star wrote the bonus track 'Grigio Girls' on her album 'Joanne' for her friend.

Recently, Gaga helped Sonja plan her wedding to her partner Andrew Dubois.
