The British singer, who hails from north London, admitted that she wouldn't mind moving in royal circles though.
'American people think I am posh even though I am really not,' she told The Sun. 'They think I have a very British accent, as in, 'Do you know the Queen?'
'I just laugh at them. In England I am thought of as common as muck.
'I'd like to know a couple of the royals, though. I'd love a night out with Prince Harry - he seems like a right laugh. I love Kate Middleton, she's brilliant. And I love William.'
When the 23-year-old isn't touring, she revealed that she loves nothing more than baking tasty treats for her pet pooch.
'I started learning to bake in August 2009 because I hadn't been home for a very long time and wanted to do something homely,' she said.
'So when I got back I got loads of cookery books and it was just me and my little dog hanging out.
'I made dog biscuits to start with, and then I started making human biscuits after Louis, my dog, showed me I had a knack for cooking.
'But I'm getting good now. The biggest fan of my baking is still my dog though. But that's not a bad thing because he has very good taste and he can smell luxury.'
