Remember when One Direction got sexy and silly on 1D Day and (among other things) danced to Jason Derulo's "Talk Dirty"? We were definitely fans. And so was Jason.
Now, 1D made the cut in Jason's new "Talk Dirty" music video, joining a mob of other celebrities who dance and sing along. Yeah, it's kind of the best thing ever.
After Harry, Zayn, Louis, Liam and Niall did the bit for 1D Day, Jason took notice, tweeting at the time: "Yooo @onedirection that was cray! i laughed dumb hard! Ppl Ya'll gotta see this! Next time invite me my dudes!!!"
Watch as 1D, Fifth Harmony, Ariana Grande, Austin Mahone, Larry King, will.i.a.m, Ryan Seacrest, Robin Thicke, Pete Wentz, Flo Rida, Jordin Sparks and more get in on the fun.
