Reese Witherspoon and Robert Pattinson will bring their Hollywood star power to the country crowd at the Academy of Country Music Awards, the ACM tells PEOPLE.

The pair, who star together as lovers in the upcoming Water for Elephants, will serve as presenters at the ceremony in Las Vegas April 3. It airs on CBS starting at 8 p.m ET.

They join a line-up that already includes hosts Reba McEntire and Blake Shelton; presenters Nancy O’Dell and Ryan Seacrest, performers Alabama, Dierks Bentley, Ronnie Dunn, Sara Evans, Martina McBride, Carrie Underwood, Zac Brown Band with James Taylor, as well as performances from the Entertainer of the Year nominees: Jason Aldean, Toby Keith, Miranda Lambert, Brad Paisley, Taylor Swift and Keith Urban.

Nashville native Witherspoon is no stranger to country music, having won an Academy Award for her portrayal of June Carter Cash in the 2005 Johnny Cash biopic Walk the Line – but the twang fest will no doubt be a new experience for the British-born Twilight series star.
