Cheryl upset at people calling her Cheryl

You know what makes Cheryl Fernandez-Versini angry? Apart from low-paid toilet attendants?

It's people not using her surname. Ooh, that makes her livid:

The X Factor judge changed her surname from Cole when she married Jean Bernard in a secret ceremony in the summer and she told Marie Claire magazine that making the change felt like the right thing to do.

"It's come quite naturally, you know", she said of getting used to her new name.

But the 31-year-old added: "People are so ignorant about it, they just start calling us Cheryl, but I'll take that, whatever."

Why would people be so ignorant? Why? Why?

It's not like you told them it'd be okay, is it?

Except when you said it was okay:

But only weeks after their wedding the pop beauty wants to be known only by her first name.

She said: “It’s just Cheryl because everyone seems to be having a hard time saying it.”

Or, indeed, when you dropped surnames altogether back in 2012, having assumed you had reached Madonna/Gandi one-name status:

The singer is reportedly dropping the name Cole - and like the music world's biggest stars, will simply be known by her first name - Cheryl.

It's hard to imagine how people could just call you Cheryl, what with you trying to use that as your personal brand and all. How ignorant people can be, eh?
