Is This the Worst Grammy Performance Ever? {VIDEO}

The 56th Annual Grammy Awards air tonight 7pm on CBS. Yes, there have been some really great performances over the years. But, some bad ones as well.

Like this one from Milli Vanilli from 1990. Bad for many reasons.  They later went on that night to win Best New Artist?  Thankfully that Grammy was stripped from them. Watch the performance and let me know what you think.
