Nicki Minaj is firing back on Twitter over criticism following her decision to cancel two performances at music festival in the UK. As RumorFix reported on Sunday, Minaj pulled out of the shows last minute after having problems with her vocal cords.

Nicki’s decision has disappointed some of her fans, causing her to explode on Twitter in a rant:

“I will NOT let you people make me feel horrible for a f*cking HEALTH issue! That’s what got me in this mess! I should’ve listened to the doctor!”

Minaj’s doctor warned her last week that she needed to rest her voice, but instead of heeding the advice, she performed a free concert in New York on Wednesday night.

“Like people are hitting me telling me I should’ve mimed. No! Then you woulda made a f*cking STORY out of that too! #killyaf*ckingself,” she writes, adding, “All you do is rip people apart and when they’re dead and gone you won’t lose a wink of sleep. #goF*ckYourselves.”

Ouch!
