Even international artists can't escape the pain of betrayal.

Lady Gaga recently ranted through social media about her personal problems.

"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," she wrote in her Twitter account. "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."

She also posted: "'Millions of dollars are not enough for some people. They want billions. Then they need trillions. I was not enough for some people. They wanted more."

Speculations point to her management team especially after she split from her long-time manager.
