With less than one month to go before the 2013 Grammy Awards, we're starting to get a more detailed picture of how the evening will play out. On Wednesday (January 16), the show got a little bit more country with Grammy winner and nominee Carrie Underwood added to the bill.

"Entertainment Tonight" got the scoop about Underwood being added to the lineup, which is stacked with other multiple nominees including six-time nominees and newcomers Fun., fellow six-timers Mumford & Sons, five-time nominees the Black Keys and three-time nominees Rihanna and Taylor Swift.

Underwood is coming off a banner career year. Her singles "So Small," "Good Girl" and "Blown Away" were all certified platinum (reflecting 1 million downloads each) in 2012, while "Jesus, Take the Wheel" ascended to double-platinum. Her most recent album, Blown Away, which was released last May, attained platinum status in September. The album's title track is nominated for Best Country Song and Best Country Solo Performance at the Grammys.

With her music climbing and topping the charts, the "American Idol" alumna kept herself very busy with a slew of musical performances: She co-starred with Steven Tyler on a CMT "Crossroads" special, made her concert debut at London's Royal Albert Hall, did a four-date swing through Australia (her first) and was tapped to play Maria von Trapp in a new three-hour TV production of "The Sound of Music," set to air live on NBC during the 2013 Christmas season.

Tune into CBS on February 10 to see all the performances at the 55th annual Grammy Awards.
