Dwayne Johnson has been flexing his philanthropic muscles all year, but the Moana star is clearly using the holidays as a chance to spread extra cheer. Dwayne hosted his annual Rock the Troops special (airing Dec. 13 on Spike) at the Joint Base Pearl Harbor-Hickam in Hawaii. The show aims to honor, inspire, and entertain the brave men and women of the Armed Services, and features tributes and performances from Nick Jonas [1], Matthew McConaughey [2], and Dwayne's BFF Kevin Hart [3] — but The Rock took the stage himself during the show for a rousing, spot-on rendition of the Elvis Presley classic "Jailhouse Rock." In the clip, Dwayne shakes his stuff while decked out in full star-spangled Elvis attire, and fulfills his role as Sexiest Man Alive [4] by charming a group of female soldiers. Watch the clip above, then see Dwayne putting his musical chops on display [5] with Lin-Manuel Miranda [6].
