*LL Cool J and his “NCIS: Los Angeles” co-star Chris O’Donnell will co-host the Academy of Country Music’s television special “ACM Presents: An All-Star Salute to the Troops.”

The show will be taped April 7 at the MGM Grand in Las Vegas — the day after the ACM Awards are held — and will air May 20 on CBS, the home network of the “NCIS” franchise.

Luke Bryan, Tim McGraw and Keith Urban have been added to a lineup that already includes George Strait, Merle Haggard, Carrie Underwood and Lady Antebellum.

The annual special carries a different theme each year. This time it will be focused on members of the military and their stories.
