Bbc bosses have been left baffled by Dizzee Rascal's Twitter.com rant against their track selection, insisting three of his new songs are on their playlist.

The British rapper slammed Radio 1 chiefs in a furious tirade on Tuesday night (05Nov13), accusing them of favouring American artists and insisting they are "full of s**t".

He even turned on several fans who failed to back his argument, but now bosses of the flagship station have hit back, insisting they have no idea why the Bonkers hitmaker flipped.

In a statement issued to NME magazine, a Radio 1 spokesman says, "Radio 1 has given Dizzee huge support over the last decade, and while not every song can make the cut, we have playlisted three singles off his current album, so we were very disappointed and really surprised to read these comments."
