The Safe Haven costars jumped on the viral video train at the premiere for their romantic flick in Berlin and no surprise, the Dancing with the Stars diva knows how to break it down.
Sky-high Brian Atwood heels and a pretty pink Zuhair Murad dress certainly didn't stop the dancing queen from getting her Harlem shake on. And Julianne is all smiles as she whips her blond hair, waves her arms in the air and kicks up her tulle skirt like a pro.
Daddy-to-be Duhamel also took part in the premiere fun, breaking it down in his Boss suit and showing off his shaking swag. Fergie's other half kicked off the viral dance—German flag in hand—before Julianne and the crowd joined in.
This isn't Josh and Julianne's first rodeo with the Baauer-inspired crazy dance—the costars also participated in a Harlem Shake tutorial (no, really) at the U.K. screening for the flick .
