The Oscars may have acted like hosts are expendable, going hostless for a second year in a row, but other shows still make finding the right host a priority.The Academy of Country Music announced last week that Keith Urban, their reigning entertainer of the year, will host the 55th annual ACM Awards on April 5. Urban is well-qualified to host the show: He's a 15-time ACM winner and a TV star, thanks to his four-year stint as a judge on American Idol from 2012-16.
