Kourtney Kardashian and Travis Barker didn’t exactly get a hero’s welcome at a WWE event — instead they got bodyslammed with a chorus of boos.

Yup, it all went down at WWE’s Money in the Bank at the Intuit Dome Saturday night — the big screen panned to Kourtney, Travis, and baby Rocky … and the crowd booed like they’d just seen the ultimate supervillains crash the ring.

Sure, a few claps here and there — but the boos were loud and clear as Travis threw up a peace sign and Kourtney kept her eyes on baby Rocky. Hard to tell if they noticed … or were just pretending not to.

Nonetheless, if they did hear it, they played it like pros — total tag team energy, powering through without a care in the world.
