Chris Tucker was caught doing his best Michael Jackson impression while shooting scenes for "Rush Hour 3" in downtown Los Angeles on Saturday.

While shooting continues today, the squeaky-voiced funnyman gets to enjoy the beautiful L.A. weather, while office workers in the area aren't so lucky; some won't be allowed to leave their buildings all day!

Tucker is making a cool $25 million on this film, guaranteeing an extra-squeaky performance.
