As if getting some tasty treats from the superstar wasn't enough, she also joined the eager movie watchers in the audience for the screening. And yes, she wore the 3-D glasses (and still looked adorbs).

"Had tons o' fun in London today at a surprise screening...Wish I could sit w/ all of u when u see ," Perry tweeted.

Part of Me will be released in theaters on July 4.
