Xzibit has slammed celebrities like Chris Brown, Justin Bieber and Katy Perry for publicising the new 'planking' craze.
Music stars including Kings Of Leon, Chris Brown and Justin Bieber have all posted pictures of themselves planking on Twitter, which involves posing for a photo while lying face down in an unusual public place.
The rapper has now hit out at 'planking' over his Twitter: ''Planking is THE dumbest s*it ever.''
''Planking was a way to transport slaves on ships during the slave trade, its not funny. Educate yourselves.''
Meanwhile, Katy Perry's attempt to join in the current craze for 'planking' has been criticised by fans on Twitter.
