A former crew member of pop star Lady Gaga has branded her a bully and monster.
The 27-year-old, who has repeatedly spoken against bullying, has been accused of unpredictable behaviour, reports contactmusic.com.
The crew member who worked on her "Monster's Ball" world tour between 2009 and 2011 said: "She would have a prayer circle before each show.
"One night she just suddenly turned on one of the backing singers, branding her unprofessional and ungrateful. She crucified her in front of dozens of people, she skinned this girl alive. It was so painful to watch and no, you couldn't step in.
"She offers support to her fans who are victims of bullying and calls them her monsters, but she is a bully and a monster herself," added the crew member.
