While most of us were resting on Labor Day, Katy Perry was busy being a party planning queen!
Even though she definitely deserved a day off, there's no rest for entertainers!
And we're sure Katy's hard work paid off because gurl entertained a house full of celebs during a Labor Day party at her Hollywood home (above). But, of course, she did it up casual Katy style with beer to drink and ping pong to play!
She reportedly invited Ellen Page, Jesse Metcalfe and his girlfriend Cara Santana, Julianne Hough, and Fifty Shades of Grey author E.L. James. What?! No John Mayer?! Should we start worrying and keeping an eye on their Facebook status?
Well, even though he apparently didn't stop by, it seems Khloe Kardashian DID make an appearance! Despite Khloe having her hands full with the whole sad and troublesome Lamar Odom sitch, we're glad to hear she's giving herself a break from time to time.
And who better to have a Roaring good time with than Katy who has been through it all with relationships…and survived!
Ch-ch-check out some more of the party pics (below)!
