I THINK this idea started when Josh and Julianne were in the KS95 studio's with Ryan and Shannon, but that cannot be confirmed at this point...

It seems at the beginning of each premiere for their new movie "Safe Haven", The future Mrs. Seacrest and Fergies baby-daddy, get the audience up.. and do a little video to the Harlem Shake!

Here they are at the Berlin premiere, but you can find vids from all over the world on the Interweb!

Fergie has been teaching that man some moves!
