Nicki Minaj has been branded a "temperamental diva" following an alleged outburst against a beautician.
The 'Super Bass' hitmaker reportedly launched a verbal tirade against Dawn DaLuise after having her eyebrows and lip waxed.
After giving out a tongue lashing, Nicki is claimed to have thrown money at the celebrity facialist and stormed out of her Dawn DaLuise Skin Refinery clinic in Los Angeles.
Dawn told America's Star magazine: "After I waxed her eyebrows and lip, she started screaming, 'Who the f**k do you think you are? Look what you did to my damn face! You think this s**t is worth $170?'
"It's a shame when you see a darling girl turn into a temperamental diva."
Dawn claimed it is not the first time she has witnessed rude behaviour from the 28-year-old rapper.
She recalled: "I arrived at her condo one afternoon, her eyes were dilated, her wig was falling off, her face was covered in red sores and she was perspiring heavily. She was swearing and screaming at her assistant."
Dawn's claims come weeks after police were called to Nicki's house following an argument with her maid.
The music star dismissed one of her workers two weeks before the incident after she took a picture of the singer taking out the rubbish and asked her to sign it and Nicki reportedly mistook a current employee for the woman when she encountered her at home, leading to an altercation.
After the current maid refused to leave, she is said to have told Nicki that she would not be "treated like an animal" while the 28-year-old star replied "I'll show you how to treat someone like an animal ... get the f**k out of my house!"
Nicki's boyfriend - who is thought to be her assistant Safaree Samuels - then reportedly pushed the woman before police were called by her boss.
A battery report was also filed although no arrests were made at the scene.
