In a very good bid for celebrity themed party of the year, Katy Perry celebrated her 32nd birthday Saturday at her own sock hop.

She presided as principal of Hudson High and documented the entire night thoroughly on her Instagram story:

Orlando Bloom was there playing basketball coach; entertainment included Marilyn Monroe, Elvis Presley, and The Supremes impersonators; and everyone played Twister on the longest board ever.

Perry even playfully dragged Bloom away from Marilyn at one point (can we also take a moment for Orlando Bloom's SHORTY SHORTS?!!?):

Basically, the night looked very, very fun—from the pie-eating contest that Cara Delevingne competed in:

To the faux classroom-turned-photo booth that everyone—Jessica Chastain, Georgia May Jagger, Kate Hudson (the other one, since Perry's real name is Katheryn Hudson)—played in.

Katy and Orlando used the opportunity to sneak in a kiss, too:

Hehe.

The appearance of Delevingne and Suki Waterhouse—two of Taylor Swift's besties—is particularly interesting, given the Perry-Swift feud isn't over. (Delevingne and Perry were last together at Burning Man in September and are both friends with Rihanna.)

Would Taylor care? Given she herself partied with Perry the week before, the answer's probably nope.
