London, Jan 29 (ANI): The last-minute pull out from Grammy’s performance following the assault last year has kept Rihanna away from taking up the stage again this year.

Both Rihanna and Chris Brown were due to sing at the prestigious ceremony in February 2009 but they cancelled their slots at the last minute after Brown left Rihanna battered and bruised.

While the ‘Umbrella’ hitmaker’s fans want her to seal her comeback with a slot at the 2010 Grammys, she insists she won’t be taking the stage after they caused the producers so much hassle last year.

“We messed their show up pretty bad last year. They might be a little mad at me,” the Daily Star quoted her as saying.

Meanwhile, the 21-year-old singer has been nominated for two awards for Run This Town, her collaboration with Jay-Z and Kanye West. (ANI)
