The singer, who has been asked to leave the UK, insisted that her native country is unsafe now that people know she fled President Mugabe's regime.
She told the News of the World: "I've been in the public eye now and people there know I've fled Mugabe's regime. They will punish us if we go back. They're going to know where we are.
"We're going to be very unsafe. People have already been approaching our family members.
"We think they could be working for Mugabe. And we know how brutal he can be. I would be in danger, it's blatantly obvious. My family would be in danger.
"There's a firing squad waiting for us there and they're putting me in front of it."
The star also admitted that she was "absolutely shocked" not to make it to the live shows, and claimed that the Home Office is trying to make an example out of her because of her newfound fame.
