Katy Perry has been making headlines with her current Witness Tour and the latest dispatch from the road proves that her behind-the-scenes antics are just as entertaining as her onstage performances.

The “Swish Swish” star crashed a wedding on Saturday that was being held at the Four Season Hotel, where she was staying in St. Louis ahead of her Sunday show at the Scottrade Center. Perry stayed at the reception for an estimated 15 minutes, TMZ reports, with 30 to 40 of her crew members tagging along. She reportedly planned to perform, but left early when the crowd got rowdy.

Witness: The Tour kicked off in Montreal on Sept. 19 after her latest album, Witness, peaked at No. 1 on the Billboard 200 in July.
