If you happened to be watching The X Factor on Sunday night, you'll be aware that Stormzy was a guest performer while the results of the public vote were being tallied.

The London grime artist performed his new single 'Blinded by Your Grace' with Labrinth joining him on vocals - only the recorded version doesn't feature Labrinth.

In fact, the song was a collaboration with singer MNEK, who only found out that he had been replaced by Labrinth after the fact.

He then took to Twitter to air his grievances...

Stormzy took to Twitter himself to explain the situation, but it appears that wires were crossed somewhere along the line...
