Mark Ronson and Bruno Mars have been accused of plagiarism.
The pair have come under fire from Serbian singer Viktorija - whose real name is Snezana Miskovic - who claims their chart-topping collaboration 'Uptown Funk' is a rip off of her 1984 single 'Ulice Mracne Nisu Za Devojke', which translates as 'Dark Streets Are Not For Girls'.
She said: "Their song 'Uptown Funk' contains 80 per cent of my tracks. How much of it are you allowed to take as inspiration for your song?"
Despite claiming the song is "80 per cent" hers, the 56-year-old star insisted she has not yet decided whether to sue them and instead just wants to have her contribution appreciated.
She told the Daily Star newspaper: "I'm in no hurry to sue them, these processes take a long time, and my life and career does not depend on lawsuits.
"For these lawsuits, there should be a lot of money, the lawyers are working on a percentage.
"If I still decide to sue them and I win, I have to figure out what to do with that money."
