The fiancée of murdered journalist Jamal Khashoggi has urged US pop star Justin Bieber to not be “a pawn” of the Saudi crown prince and to cancel his performance at a Formula One event in Saudi Arabia.

Axar.az reports that Cengiz asked Bieber not to be “a pawn” of Saudi crown prince Mohammed bin Salman, whom she called a “killer.”

“This year, you released an album that you titled ‘Justice.’ You also released one titled ‘Freedom.’ Saudi Arabia is in dire need of both,” Cengiz wrote. “Your message will be loud and clear: I do not perform for dictators. I choose justice and freedom over money.
