Katie Couric will get up close and personal with country music's leading ladies this Friday in a special 'All Access Nashville' episode of '20/20.'

The host will sit down with Taylor Swift at the famed Country Music Hall of Fame, and will even get a chance to enter the 'Begin Again' hitmaker's home, where Swift will admit one of her biggest fears. The timing is great for the 22-year-old singer, who is in the midst of a media blitz following the release of her critically-acclaimed fourth studio album, 'Red.'

Meanwhile, Carrie Underwood, Reba McEntire and Miranda Lambert (with her fellow ladies of Pistol Annies, Ashley Monroe and Angaleena Presley) will also give Couric a peek inside their personal lives. But that's not all -- Luke Bryan, Martina McBride and Jason Aldean will talk about the greatest female country singers of all time.

'All Access Nashville With Katie Couric - A Special Edition of 20/20' will air Friday (Oct. 26) at 9PM ET on ABC.
