Liam Hemsworth and Rebel Wilson Dance in the Street for Upcoming Movie

Liam Hemsworth's got moves -- choreographed moves -- as do a few of his costars in their upcoming romantic comedy.

Liam was spotted dancing in front of a building with Rebel Wilson and other "Isn't It Romantic" cast members in NYC Saturday morning. It's hard to tell for sure, but it looks like Adam DeVine is one of them ... to the right in the vid.

This isn't the first time we've seen Liam and Rebel together for this film either -- although last time ... it was for a moist makeout session.
