An X Factor source told The Sun Cheryl 'looked really peeved. She said, 'Cole is not my name!'"
She was particularly annoyed because her new husband Jean-Bernard was sitting in the audience, and Ian's excuse for the mix-up didn't wash with her.
The source continued: "Royce said he had trouble pronouncing it but she gave him a withering look and said it wasn't hard to say 'unless you were arrogant and had no common sense'."

Simon Cowell's ex and wing woman Sinitta confirmed that Chezza does not appreciate people calling her by her former name.
She said: "Do not use the C-word in this building. The four-letter C-word, cole."
But Cheryl didn't stay mad at Ian for too long, with the source adding: "She and Roycey have now kissed and made up."
Cheryl divorced footballer Ashley Cole, 33, in 2010, after multiple reports of his infidelity.
She and Jean-Bernard married earlier this year in a secret ceremony on the island of Mustique.
