What do One Direction, Ariana Grande, Flo Rida, Austin Mahone, Ryan Seacrest and, um Larry King have in common?
Nothing, really, except they are among the dozen-plus celebs who make cameos in a new all-star edition of the video for Jason DeRulo's hit, "Talk Dirty."
The "Celebrities Talkin' Dirty" clip dropped on Wednesday (March 14) and like Carly Rae Jepsen's star-packed "Call Me Maybe" video and Bonnie McKee's A-list "American Girl," DeRulo clearly called in a bunch of favors for the second clip for Middle Eastern-vibed top 5 Billboard hit.
Who answered his call?
1. One Direction — at various points we see Niall Horan (in his underwear!) and Harry Styles dancing shirtless while Liam Payne and Zayn Malik bust some backstage moves in the green room.
2. Fifth Harmony — The girls shake it for the camera.
3. Trevor Moran — The YouTube star shows off his swag in a tuxedo.
