LAS VEGAS - Sour grapes from Kanye West again. Shut out at the Video Music Awards, Kanye West threw a tantrum Sunday night in front of media and crew backstage as the MTV show was ending.

West, waiting for an elevator in a crowded hallway, began yelling about losing all five categories for which he was nominated.

"That's two years in a row, man ... give a black man a chance," West said, stomping around his entourage and directing his comments at a reporter. "I'm trying hard man, I have the ... number one record, man."

West said he never will return to MTV.

The rapper was nomination for five awards, including male artist of the year. This is the latest in a series of awards show outburst for West. Last year, he crashed the stage at the MTV Europe Awards after not winning for best video.
