Lady Gaga has revealed that she resourced strength and courage from her fans as she underwent hip surgery.

As previously reported, the singer recently cancelled all the remaining dates on her Born This Way Ball tour due to a troublesome hip complaint.

She entered the operating theatre yesterday (January 20) to have hip surgery to fix the issue.

In an emotional letter posted on her Little Monsters website after the operation, Gaga later paid tribute to her fans and revealed that she is looking to them for inspiration during the troubling times. The 'Marry The Night' star said:

"Monsters, You really gave me a lot of strength today. Everything happened so fast, but when it came time to face it I reflected on the many stories and experiences you've shared with me about your lives. Meeting you backstage, reading your letters, watching you communicate with fans from around the globe to form a community that supports one another -- You have completely blown my mind."

She continued: "As they wheeled me into surgery today, I thought about all of your pain and perseverance,  your unique family situations, school environments, health issues, homelessness, identity struggles -- sometimes you are so brave that it terrifies me. I wonder how it's even possible. So I thought to myself, I'm alive, I'm living my dream, and this is just a bump in the road. I'm grateful because this is temporary, and for some it is not. You have changed my life. I love you and am proud to be a part of your lives. If you can do it, I can do it too, and if we stick together we can get through anything. Love, Gaga."
