Good news / bad news time for Rihanna.
First the good news.....
Last year the Barbadian sensation picked up her first Grammy, with Jay-Z for "Umbrella".
Now she is poised to add at least one more Grammy to her collection.
Her single "Disturbia" is up for Best Dance Recording and "If I Never See Your Face Again", her collaboration with Maroon 5 is up for Best Pop Collaboration With Vocals.
Rihanna will also be performing Sunday night at the awards ceremony.
And now the bad news.....
Manu Dibango, a Cameroonian singer, sued Michael Jackson for stealing the line ?mama-say mama-sa ma-ma-coo-sa? from Manu's ?Soul Makossa?.
Jackson admitted to ?borrowing the line? and they settled out of court.
But Rihanna used the line in her song ?Don?t Stop the Music? after she got permission from Michael, not Manu.
So now Manu is suing her for more than $600,000.
