Rihanna had some choice words -- four letter ones, at that -- for critics of her behavior at last weekend's Coachella festival.

MTV posted an article expressing concern over the 'Where Have You Been' singer being photographed smoking a helluva lot of weed at the festival, at one point even rolling a cigar on her bodyguard's head. (Seriously, RiRi? Give that guy a raise.) When MTV tweeted a link to the post, writing, "Yikes. @Rihanna's marijuana photos from Coachella spark controversy," it didn't sit well with the starlet.

Rihanna promptly replied, "Yikes.... @rihanna ran out of f---s to give."

MTV, who deleted their original tweet to the Bajan blunt enthusiast, responded with a curt "Well played. (Still <3 <3 <3 you.)" For her part, Rihanna seems to have forgiven the network, replying, "That's the hook right thurr #1LOVE."

Rihanna seems to be buying into her own poor role model persona, but she may want to reconsider after being named one of Time Magazine's 100 Must Influential. Her party girl rep has earned the ire not just of a bit of the media, but also of Cissy Houston, who allegedly refuses to let RiRi have any role whatsoever in any potential Whitney Houston biopic.

Our advice? Rihanna's a rockstar who can do what she wants ... But she may want to start doing it more in private.
