Joss Stone says people who mocked her US accent have personal problems.
The Devon-born singer - who shocked people with her pronounced US drawl at the BRITs last month - says she doesn't understand why people criticised her accent.
Joss told Britain's Radio 1: "The sound of my voice and my accent doesn't mean anything.
"If people have a problem with it - that's their own inner problem.
"I've been in America since I was 14. That's why I sound the way I do."
The 19-year-old Tell Me 'Bout It singer insists she still has the right to moan about her job because singing is "hard work".
She said: "Everyone moans about their job. I don't see why I'm not allowed to moan.
"It's hard work and I'm tired and if I want to moan, I'll moan."
