Two of country music's greatest -- Miranda Lambert and Ronnie Dunn -- will appear for a press conference at the Country Music Hall of Fame and Museum in Nashville on Feb. 1 to unveil the nominations for the 46th annual Academy of Country Music Awards.

The nominees for Top New Solo Vocalist (Easton Corbin, Randy Houser, Eric Church) and the Top New Vocal Duo or Group (the Band Perry, Steel Magnolia, JaneDear Girls) were announced earlier this month, with fan-voting to begin Jan. 27 and run through the end of February.

Lambert and Dunn are no strangers to ACM nods -- the 'White Liar' singer and member of the Brooks and Dunn duo have 21 awards between them. Just last year at the 45th annual ACMs, Lambert took home Female Vocalist of the Year, as well as awards for her album 'Revolution' and smash hit 'White Liar.'

The 46th annual Academy of Country Music Awards, co-hosted by Reba McEntire and Blake Shelton, will be broadcast live from the MGM Grand Garden Arena in Las Vegas on Sunday, April 3, on CBS.
