Many stars have been critical of Brown's Grammy night lovefest

After performing — and winning! — at the 54th Annual Grammy Awards on Sunday, Chris Brown caused many to wonder whether the 2009 domestic abuse incident that left then-girlfriend Rihanna bruised and beaten could be so easily forgiven. Miranda Lambert, Eric Stonestreet, Michelle Branch and Jack Osbourne were among many celebs who expressed disapproval of Brown's Grammy lovefest on Twitter — to say nothing of everyday music fans who also erupted with cries of disdain for CBS, Brown and Grammy voters.

Brown's response? "Hate all you want cuz I got a Grammy now! That's the ultimate f*** off," he tweeted, in a series of posts that have since been deleted. The angry/smug tweets and their subsequent cover-up understandably fanned the flames directed at Brown, many of whom describe him as a "wife beater."

Brown pleaded guilty in 2009 to felony assault against Rihanna for an incident that occured the night before the Grammy ceremony that year.
