Dido or Britney?

Britney Spears Forum

DIDO was mistaken for Britney Spears on America's Late Late Show.

The British star was backstage when intern Craig Kilborn approached her and said: 'I dig your music Britney.'

The star laughed it off, but when the show's producers heard about the slip-up, they made Craig appear live on the show so Dido could wreak her revenge.

When Craig repeated what he said, the singer launched at him with a foam pie.

Was he joking? Just to set up something? Or was he serious? You would think the host of a music show would get the names of the guests on the show right?
