Lady Gaga Writes The Most Touching Tribute To Her Late Friend Sonja — PHOTO

After battling cancer for years, Lady Gaga's best friend Sonja Durham recently passed away, according to Entertainment Tonight. Gaga — who wrote the song "Grigio Girls" on her latest album, Joanne, about Durham — confirmed the news in a brief Instagram post on Thursday, May 18. "Watching one of my best friends in the world show unfathomable courage, strength, and positivity while battling cancer has really changed my life," the singer shared. On Sunday, Gaga shared another photo of herself and Durham to social media along with a lengthier and incredibly touching tribute to her late friend.

"I don't know how to put a price on a friendship," Gaga captioned the photo. "I'm not even sure how you can assess the size of its meaning, only really your heart truly knows and it's too special for words." Gaga continued to explain that she was feeling "two competing feelings" regarding Durham's passing. The singer said,

It's such a vulnerable and emotional statement, and one that truly makes you stop and think about appreciating the people in your life.

Gaga finished her tribute to Durham by discussing how she planned to move forward, saying,

I actually remember hearing "Grigio Girls" for the first time when Joanne came out. I didn't even realize the song was written about one of Gaga's best friends, but as I listened to the song I noticed tears swelling in my eyes. The emotion in Gaga's voice touched me, and I could tell that the song was a personal message from Gaga to someone special in her life. I can only imagine how difficult of a time it must be for Gaga and the rest of Durham's family. My heart goes out to them.
