Jamelia has accused the police of racism, saying she is regularly pulled over when she is driving.
The singer, 30, said that she was stopped "at least once a month" because of the colour of her skin.
Writing on Twitter, she said: "The amount of times I've been pulled over for nothing is ridiculous... racism is alive and kicking people".
She told her followers: "I was not even driving, I was sat in my car parked up.
"They said to me they have reason to believe my tax disc is counterfeit. When I asked them what this 'reason' was, they were stumped."
The Superstar singer added: "They checked everything... including my tyre pressure (all legit). They then went on to say they don't see how this ... can be my car!
"They didn't know I was Jamelia when they approached me, they just saw a black girl in an Adidas tracksuit and cap, in an expensive car."
The mother of two, who did not say where she was stopped, added later: "I'm over it now."
