Joining McEntire as the hall's newest members are songwriter Bobby Braddock and singer Jean Shepard. The 2011 inductees were introduced Tuesday at the Country Music Hall of Fame and Museum.
McEntire has been in the business for three dozen years. The 55-year-old country icon has sold more than 55 million albums and recently scored her 35th No.1 hit.
Braddock is the first inductee in the new songwriter category. He's written hits for George Jones, Tammy Wynette and Toby Keith, and nine of his songs have been played more than 1 million times on the radio.
Shepard is known as "The Grand Lady of The Grand Ole Opry" with hits stretching back to the early 1950s.
