Leave it to Chris Brown to turn something overwhelmingly positive like winning a Grammy into an opportunity to act like a whiny b!tch.

Three years after his notorious Rihanna assault, Chris gave two Grammy night performances and took home an award. Some celebs were unhappy with such praise and attention going to a man who brutally beat and threatened to kill his girlfriend just a few years earlier, and they spoke out about it on Twitter.

"Chris Brown twice? I don't get it. He beat on a girl ... Not cool that we act like that didn't happen," said Miranda Lambert. Singer Michelle Branch agreed, tweeting, "Chris Brown ... (bites tongue) have we forgiven him?"

Never one to keep his opinions to himself, Chris tweeted yesterday, “HATE ALL U WANT BECUZ I GOT A GRAMMY Now! That’s the ultimate F**K OFF!” Chris went on to compare himself to drug dealing rappers who went on to find success in the music industry, because beating women and dealing drugs are apparently the same thing now. Perhaps realizing how idiotic he sounded, Chris quickly deleted the tweet, but the damage to his reputation has been done. How is this man still allowed to manage his own Twitter?!
