But she REALLY stepped her game up for the after-party.

The singer changed into a full-on hamburger outfit at fashion's biggest night. Check and mate.
The theme of the night was \"Camp,\" but this was next level.
According to Perry and several outlets, the outfit was designed by Moschino and came with cheese, lettuce, pickles ... basically the works. It looks as delicious as it is daring.
Fans were in awe of the effort, one writing, \"katy perry changed into a burger and the inside dress is lettuce!!!! SHE WINS!!!\" Another noted that Jennifer Lopez walks right by as she's changing outfits.

We're also inspired by the fact she was able to groove and dance in that outfit.

Well played Katy, you are certainly a \"Firework.\" We really heard you \"Roar\" last night.
OK, OK, we'll stop now.
