Vanessa Hudgens is the latest victim to get Punk'D by MTV!

The High School Musical star was hangin' out with Modern Family's Sarah Hyland in a car when they suddenly spotted a man in a truck demolishing a playhouse in the middle of an empty street before peeling out.

The girls rushed to the scene only to be met with a distressed engineer who told them that the playhouse was part of a float for a parade, and that they needed to fix it.

The girls desperately tried to help, until Vanessa realized they'd been Punk'D -- and Hyland was in on the gag!

Check out the hilarious video above, which also features The Hunger Games star Josh Hutcherson having and accidental run-in with some undercover cops!
