Update: Read the full list of 2011 ACM Awards nominees here.

The 46th Annual Academy of Country Music Awards nominations will be announced on February 1, with Miranda Lambert and Ronnie Dunn doing the honors. The pair will announce the names at a special press conference at Nashville Country Music Hall of Fame and Museum.

Miranda and Ronnie are hardly strangers to the ACMs. Miranda has earned five ACM trophies since 2006, including last year's Album of the Year. Ronnie has amassed more than 30 ACM awards, thanks to his lengthy career as one-half of Brooks & Dunn, including three Entertainer of the Year wins.

The nominees for the fan-voted categories for the ACM Awards were announced earlier this month. Easton Corbin, Eric Church and Randy Houser were named in the Top New Solo Vocalist category, while The Band Perry, The JaneDear Girls and Steel Magnolia were named in Top New Vocal Duo or Group.

Miranda will join several of her fellow female superstars for a special televised concert special, 'Girls Night Out: Superstar Women of Country,' which will air after the ACM Awards. Rumored to be included in the show are Reba, Taylor Swift and Carrie Underwood.

Sugarland will also host the first-ever ACM Fan Jam, which will take place at the Mandalay Resort & Casino during and after the ACM Awards. Fan Jam will include performances by the duo and several of their famous friends, as well as live remotes into the ACM Awards.

The ACM Awards, hosted by Reba and Blake Shelton, will air live from Las Vegas on Sunday, April 3 at 8:00 PM ET on CBS.
