So, Katy Perry threw a birthday party, and in TRUE Katy fashion, she went ALL. OUT. Even though her actual birthday was in late October (the 25th to be exact!), she continued the celebration by throwing a "Wild West Ho Down Throwdown" themed fete and invited allll of her cute-to-boot friends. I mean, we're not really THAT into theme parties, but when we were perusing through Mark The Cobrasnake's photos, we began to SERIOUSLY rethink every Cowboys and Indians college party we were invited to—our outfit could've been so much cuter. Just look at Katy! She wore a head-to-toe pink, black, and white outfit straight from Jeremy Scott's spring 2012 collection, and (as you'll see in the last photo) she even got a customized studded vest that says "Bday Gal" on the back! Adorable. Jeremy also showed up to the shindig wearing a pink and green fringe vest from his spring 2012 collection, and, um, some very revealing chaps. (Scroll down for the money shot.) Katy and Jeremy are obviously besties, and there's nothing we love more than seeing one of our favorite artists and designers collab for an all-out adorable ensemble. Other highlights from the party include: Robyn dressed up as a cactus (yes, THAT Robyn), Russell Brand as a shirtless Indian, and Katy Perry shooting another cowboy with her pink rhinestone gun. Uh-mazing. Peep TONS of photos below!!!
