Rihanna is upset over an article in a British tabloid on Tuesday referring to her as a "poisonous pop princess."

The article, published in Britain's Daily Mail newspaper by writer Liz Jones, featured the headline "Pop's poisonous princess: Glorying in drugs, guns and sleaze, Rihanna's toxic role model for her army of young fans" -- and the singer is not happy about it.

"If you sincerely wanna help little girls more than their own parents do, here's a toxic tip: don't be amateur with your articles, you sound bitter!" Rihanna lashed out via her Instagram page. "That s**t ain't journalism! That's a sad sloppy menopausal mess!!! Nobody over here acts like they're perfect! I don't pretend that I'm like you, I just live... My life!! And I don't know why y'all still act so surprised by any of it!!"

The article calls her a bad example over her raunch dance routines, wardrobe choices, scantily-clad Instagram photos and love of marijuana. A photo of Rihanna holding two giant joints during a recent trip to Amsterdam is featured in the piece, along with a photo of the singer's marijuana leaf cake from April 20 (4/20).

"Role Model is not a position or title that I have ever campaigned for," Rihanna added, "so chill wit dat! I got my own f**ked up s**t to work on, I'll never portray that as perfect, but for right now it's me!! Call it what ya want!! Toxic was cute, Poisonous Pop Princess had a nice ring to it, just a lil wordy!"
