Chris Brown accepts the award for 'Best Rap Performance' onstage at the 54th Annual GRAMMY Awards held at Staples Center on Feb. 12, 2012 in Los Angeles

*Chris Brown has some is lashing back at those who have criticized his return to the Grammy Awards on Sunday night. “F— off.”

In a Twitter rant that has since been deleted, Brown went in on the people who took issue with his worthiness to be at the show three years after he assaulted his then-girlfriend Rihanna on the eve of the 2009 awards.

“HATE ALL U WANT BECUZ I GOT A GRAMMY Now! That’s the ultimate F**K OFF!” Brown tweeted on Tuesday in a widely reported post that has since been deleted, but was preserved by the Mashable site. The site reported that a trending topic during the Grammy show was “wife beater” in reference to Brown.

“Strange how we pick and choose who to hate!” Brown reportedly wrote. “Let me ask u this. Our society is full of rappers (which I listen to) who have sold drugs (poisoning). But yet we glorify them and imitate everything they do. Then right before the worlds eyes a man shows how he can make a Big mistake and learn from it, but still has to deal with day to day hatred! You guys love to hate!!! But guess what???”

An unnamed source said to be close to Brown denied that the singer posted the comments himself, telling Radar Online that “someone does his postings on Twitter and when he saw that, he ordered it taken down immediately.”

Brown’s angry response came after a number of celebrities expressed disappointment that the singer performed twice on the Grammy broadcast. Among them were country star Miranda Lambert, who wrote, “I don’t get it. He beat on a girl … not cool that we act like that didn’t happen.” She suggested that Brown needed to listen to her track “Gunpowder and Lead” (about a woman preparing to kill her abusive husband) and “be put back in his place. Not at the Grammys.”

Jack Osbourne was not impressed either, tweeting, “Chris Brown … people don’t forget! #chrisbrownbeatswomen,” while singer Michelle Branch wrote, “Trying not to go off on a rant but … Chris Brown … *bites tongue* have we forgiven him?”

In another Tweet that has since been deleted, Brown wrote after his win for Best R&B album, “people who make mistakes and learn from them are ROLE MODELS too. I’m just happy to inspire growth and positivity.”

After a number of music critics and op-ed writers questioned the logic of having Brown return to the Grammy stage, Recording Academy president Neil Portnow defended the decision on Monday, saying the Academy’s voting helps dictate the content of the show. “If we’re going to get in trying to personally evaluate artists in terms of their personal lives, that’s a slippery slope that we wouldn’t want to get into,” he said.
