"I'm crazy, and I don't pretend to be anything else," the singer declares in a defiant tweet.

Photos of Rihanna appearing to roll a marijuana blunt at the Coachella Music Festival over the weekend have sparked online criticism of the R&B star -- but she has some strong words for the haters.

"Yikes. @Rihanna's marijuana photos from Coachella spark controversy," MTV wrote on its Twitter account on Thursday afternoon, posting shots from the singer's Instagram feed and drawing a barbed response from Rihanna herself.

"@MTV Yikes… @rihanna ran out of f***s to give," she tweeted back.

MTV has since deleted its tweet, though the story remains posted.

"I'm crazy, and I don't pretend to be anything else," Rihanna tweeted on Tuesday, in response to fans concerned by the photos.

Perhaps she was drawing inspiration from past artists: on Wednesday, Rihanna took to her Twitter page to advise fans to see the new Bob Marley documentary, "Marley."

"Bob Marley is my HERO #thatisall," she added, of the noted reggae icon and marijuana aficionado.
