Rihanna was already confirmed as performer for the 2013 Grammy Awards, but today comes word that she'll be joined on stage by two of pop music's most respected gentlemen, Bruno Mars and Sting. The Recording Academy announced the news in a press release that also revealed that Record of the Year nominee Kelly Clarkson will be performing during the ceremony.

It will be interesting to see how RiRi, who is up for three awards, teams up with Mars and Sting. Mars has one career Grammy win and is a nominee this year as a featured artist on Snoop Dogg and Wiz Khalifa's 'Young, Wild & Free,' while Sting has won 16 Grammys throughout his lengthy career.

Clarkson is a contender for three awards this year for her 'Stronger' single and album. The soon-to-be-married singer has two previous Grammys to her credit, both in 2006 for her 'Since U Been Gone' single and 'Breakaway' album.

In other big news, Prince and Beyonce, who performed together at the 2004 Grammys, will appear at this weekend's ceremony as presenters. Other confirmed presenters for the broadcast include Jennifer Lopez, Katy Perry and Carly Rae Jepsen.

The 2013 Grammy Awards air this Sunday, Feb. 10 at 8PM ET. Previously announced performers include Justin Timberlake, Taylor Swift, Frank Ocean, Fun., the Lumineers, Ed Sheeran with Elton John, and Alicia Keys with Maroon 5.
