The rapper compared the industry to being back in the classroom.
She told Teen Vogue: "People treat this business like it's high school.
"It can absolutely feel like one big popularity contest, and you know what? I can't be bothered. I can't allow myself to play ridiculous games with grown adults in the industry."
The star, who has engaged in a public feud with fellow American Idol judge Mariah Carey, said: "I can't be nice to someone just because they're hot right now. I can't do it."

Read the fine print on a contract. If you're not happy with the proposed terms of a deal, renegotiate. Don't be afraid to drive a hard bargain. You may not realise it, but you have a great deal of power. People are willing to pay good money for someone with your intelligence and experience. If you undersell yourself, you will set a dangerous precedent. Someone will ask you to do something that goes against your conscience. Obey your principles, even if it means making an enemy.More
