Rihanna to Perform on The Voice Season 3 Live Finale, Dec. 18, 2012

Dec. 18 is a big day for everyone on The Voice. No, we’re not talking about Christina Aguilera’s highly-anticipated 32nd birthday — we mean the Season 3 finale!

The day just got a little bit sweeter now that NBC has announced the finale’s star-studded guest performances. Rihanna, Kelly Clarkson, Bruno Mars, and The Killers will all hit the Voice stage during the live two-hour finale.

Today, pop star Rihanna took to Twitter to express her excitement, saying, “Watch me perform on #TheVOICE finale airing December 18th.”

We hope RiRi will “shine bright like a diamond” with her new hit single, “Diamonds,” come Dec. 18. This marks Rihanna’s first appearance on the show, but certainly not the first time we’ve heard her music on the Voice stage.
