J. Lo Unfazed By Katy Perry's Cheeseburger Change in Bathroom During Met Gala

J. Lo has seen it all, so when she ran into Katy Perry changing into a cheeseburger costume at the Met Gala, it was just another day at the office.

The "World of Dance" judge seemed totally unfazed when she found herself in the bathroom at the star-studded event on Monday with Perry slipping out of her chandelier costume and into another camp-inspired look.

J. Lo laughs as she glides past the singer, who's frantically transforming into a delicious snack.

Not all celebrities at the Met were as calm and collected as J. Lo over Perry's look.

She was the hit of the party singing and dancing withGwen Stefani during Cher's performance, and Bella Hadid totally lost it when she saw Perry's first look.
