Although the nominees will not be revealed until the Wednesday concert, report suggested Nicki Minaj, Bruno Mars and Janelle Monae will not be listed as New Artist contenders.

Minaj and Mars reportedly are ineligible for the category because they didn't release their debut albums between October 1, 2009 - September 30, 2010, a Grammy eligible period of time. "The current eligibility requirements state that the artist must have released, as a featured performing artist, at least one album but not more than three," according to the rules.

As for Monae, she allegedly is not allowed for New Artist battle because she has released a mini album "Metropolis, Suite I: The Chase" and got one nomination at 2009 Grammys for one of its songs. According to a Recording Academy representative, anyone who previously got a nod for a "body of work" such as an EP or full LP, is not eligible in the new artist category.
