Lady Gaga has revealed that she was left heartbroken when she realised that some of her friends were only using her for her fame.

Last year singer had to cancel shows to have hip surgery and in a post on her website she opened up to her fans about certain friends that only seem to care about her while she's in the spotlight.

The post reads, "My heart breaks from the people I have trusted and loved who I've worked so closely with, who have used me, lied to me, worked me into the ground for the personal gain.

"When I woke up in the hospital after my surgery there were many people that were not there. My health did not matter. I did not matter unless I could perform. This is a very hard lesson."
