Chris Brown doesn't care if you're upset that he performed and won an award at the Grammys.

Some people on Twitter - most notably country singer Miranda Lambert - questioned why Chris was getting so much love from the Grammys just three years after he assaulted his then-girlfriend Rihanna. Lambert tweeted after Sunday's ceremony, "Chris Brown twice? I don't get it. He beat on a girl. Not cool that we act like that didn't happen."

According to E! Online, Chris lashed out at his critics by tweeting, "HATE ALL U WANT BECUZ I GOT A GRAMMY Now! That's the ultimate F**** OFF!"

He later deleted the tweet and wrote, "IM BACK SO WATCH MY BaCK as I walk away from all this negativity #teambreezygrammy."

The second tweet also has since been deleted from his account.
