It won’t only be top nominees Lady Antebellum, Miranda Lambert, Carrie Underwood, Taylor Swift and host – for the 12th time – Reba McEntire who’ll generate heat at Sunday’s Academy of Country Music Awards in Las Vegas.
Eddie Cibrian, Josh Duhamel, Faith Hill and Lindsay Vonn have joined the roster of presenters to the event, its organizers tell PEOPLE. The 45th annual ACM Awards show will be taped live and broadcast on CBS at 8pm ET/delayed PT.
And while Nashville is in Nevada, ACM Presents: Brooks & Dunn – The Last Rodeo, a tribute special, will tape in Las Vegas on Monday night and air on CBS May 23.
Previously unannounced guest stars include performers Faith Hill, Tim McGraw and Darius Rucker – and presenters Matthew McConaughey, Miranda Cosgrove and the poet Maya Angelou.
