R&B star Solange Knowles is fuming after her Twitter account was targeted by an internet hacker.
 
The singer's blog on the social networking site was updated on Friday afternoon with a message championing the affects of a diet product and providing followers with a link to purchase the weight-loss aid.
 
The post read: "remember that diet I tryed (sic) it works!"
 
Knowles spotted the hoax an hour after it had been uploaded and quickly took to her blog to warn fans that her page had been hacked, insisting she would never endorse such a product.
 
She wrote, "What in the fuggggg (sic)!!! I got hacked! Y'all know my lil a** ain't (sic) lost no 40 pounds... Sorry to all who actually ordered that. Sounds like crack in a bottle. And not humanly possible."
