We're just four days out from the April 1 live telecast of the 47th Annual ACM Awards, and the Academy is still unrolling names of country stars who will be performing and presenting this year. Today, the list continued to grow as it was announced that Brad Paisley and Dierks Bentley will the the two newest additions to the continually growing celebrity cast, which already includes big names like Keith Urban, Carrie Underwood, Tim McGraw and tons more.

In addition to announcing the two newest performers added to the lineup, the Academy also revealed two more huge stars who are slated to present prestigious awards on Sunday night: Taylor Swift and Lionel Richie. Richie will also be hosting the April 2 concert which follows the main event, which we will turned into a show titled ‘ACM Presents: Lionel Richie and Friends in Concert.' That will air on CBS on April 13. This weekend, Swift and Richie will be joined by presenters Nancy O'Dell, Hunter Hayes and Beth Behrs.

Paisley netted the Male Vocalist of the Year Award in 2011, and this year he's up for four awards, one of which is his fifth consecutive nod for Entertainer of the Year and his eighth nod for Male Vocalist of the Year -- an award he's landed five times since 2006. His remaining two nominations in 2012 are for Vocal Event of the Year for 'Old Alabama' featuring Alabama, as well as another in the same category for his power duet 'Remind Me' with Underwood.

Of course, Bentley is no stranger to the annual awards either, garnering a double nomination both as an artist and a composer for Song of the Year for his single 'Home,' the title track of his Feb. 7. In the past, Bentley has taken home the ACM Award for New Artist of the Year, and he's scored nominations for Album of the Year for 'Up On the Ridge' and Male Vocalist of the Year.

Catch Paisley, Bentley and the rest of the star-studded country gang set to appear on the ACMs Sunday, April 1 on CBS beginning at 8PM ET.
