Reba McEntire will host the Academy of Country Music Awards show for the third straight year. And for the second consecutive year, the event will take place in Las Vegas at the Mandalay Bay Resort & Casino. Two years ago, McEntire was awarded the ACM's first annual Home Depot Humanitarian Award for her charity work. She is the all-time leading winner in the ACM's top female vocalist category. The May 26 awards show will be televised live on CBS.
