This past weekend was a pretty big deal for celebs. Obviously, the Grammys were at the weekend, where all your favourite musicians showed out in their best and brightest lewks. On top of that, the BAFTAs happened. But even with all that, perhaps the biggest event of the week was Jennifer Aniston's 50th birthday party.

To put it mildly, the bash looked absolutely f*cking lit. Pretty much everyone in Hollywood was there, including Katy Perry, Kate Hudson, Gwyneth Paltrow, Orlando Bloom, Ellen DeGeneres, Demi Moore, John Mayer, Reese Witherspoon, and literally so many more. Oh, and Jen's ex-husband, Brad Pitt, was there too. Casual!

Apparently Jen enforced a total social media ban (what happens at the party STAYS at the party), but thanks to some of her rule-ignoring friends, we got a small glimpse of the craziness that went down.

Katy Perry decided to call Kate Hudson out for posting her (very cute) pics by commenting "NO SOCIAL MEDIA," but Kate kindly clapped back by claiming she "got permish." Okay girl!

Guess our invite got lost in the post.
