The party's over for Malia Obama! After RadarOnline.com released the shocking video of an eyewitness accusing President Obama's 18-year-old daughter of smoking pot, furious Barack confronted the teen on their summer vacation, said a source.

The source said that Barack went into crisis mode after the "First Wild Child" had to be hauled out of a house party on Martha's Vineyard — just before local cops went in for a raid!

Sgt. Skip Manter with the West Tisbury Police Department confirmed that neighbors "complained about noise."

Malia, 18, was hurried out of the rowdy bash by Secret Service right before police arrived.
