What do One Direction, Ariana Grande, Robin Thicke, the “Pawn Stars” guys and Larry King have in common?

They’re among the nearly two dozen famous faces who appear in the new celeb-filled version of Jason Derulo’s “Talk Dirty” music video.

Also lip-syncing Jason’s pop hit in the music vid are his girlfriend Jordin Sparks, Austin Mahone (who has an impressive shimmy, by the way), will.i.am, the girls of Fifth Harmony, Ryan Seacrest and Ellen K, Pete Wentz, Bret Michaels, Emblem 3, Tyler Posey, Enrique Iglesias and more.
