At his MySpace page, there's a plea for fans to vote for Brown in two top races — favorite song, in which he's nominated opposite Rihanna — and favorite male singer. The request for support was posted one day after online voting commenced Monday.
In the face-off for best song, Chris Brown competes with his No. 1 single "Kiss Kiss" opposite Rihanna's "Don't Stop the Music," Beyonce's "Single Ladies (Put a Ring on It)" and Katy Perry's "I Kissed a Girl." In the race for favorite male singer — a prize he won last year — Brown squares off against his "Kiss Kiss" collaborator T-Pain, 2006 winner Jesse McCartney and Kid Rock. Brown also competed in the category in 2007, but lost to Justin Timberlake.
Rihanna is nominated for favorite female singer for the first time, taking on last year's champ Miley Cyrus, 2007 winner Beyonce and three-time nominee Alicia Keys.
The Kids' Choice Awards will not mark the first time that Brown and Rihanna have been rivals in the same category. Last year Rihanna and Jay-Z ("Umbrella") beat Chris Brown and T-Pain ("Kiss Kiss") at the Grammys for best rap/sung collaboration.
At this year's Grammys, they both contended in the pop vocal collaboration category. Brown and Jordin Sparks were nominated for "No Air" while Rihanna and Maroon 5 were up for "If I Never See Your Face Again." They lost to Robert Plant and Alison Krauss ("Rich Woman").
There is no word on whether either Brown or Rihanna will attend the Kids' Choice Awards, which will be telecast live on Nickelodeon and hosted by "The Rock," Dwayne Johnson. They both skipped the NAACP Image Awards, which came only five days after the Grammy-eve incident that catapulted them into the headlines. At the Image Awards, Brown lost the male vocalist prize to Jamie Foxx, and Rihanna was bested by Beyonce for female vocalist.
