Katy Perry left children in tears at a recent birthday party where she dressed up like a clown, attacked some guy with a piñata stick, and staged a scary car accident … all for a music video — and TMZ has video from the scene.
The hidden camera gag was shot at Knollwood Country Club outside L.A. earlier this month for Katy’s “Birthday” video — Katy showed a little preview on “Jimmy Kimmel Live” Monday night … but her clip didn’t include the crazy fallout.
Eye witnesses tell TMZ, Katy pranked a REAL 5-year-old’s birthday party … and most guests had no idea they were getting punk’d. Children were crying. One woman stormed away, visibly upset.
