Katy Perry Slams Kate Hudson & Gwyneth For Breaking Jen Aniston’s Bday Party Rule

Sure, The Grammys were a pretty huge deal but did you hear about the WILD birthday party Jennifer Aniston threw to ring in her 50th year of being a living, breathing goddess?

The IRL Rachel Green invited scores of her celebrity pals to celebrate with her at the Sunset Tower Hotel in Los Angeles, including a bunch of her exes and their exes, I might add.

People reports that party guests included Brad Pitt, Gwyneth Paltrow, John Mayer, Katy Perry, Orlando Bloom, Lisa Kudrow, Courteney Cox, David Arquette, George and Amal Clooney, Reese Witherspoon, Robert Downey Jr., Ellen DeGeneres, Barbra Streisand, Keith Richards, Kate Hudson, Laura Dern, Demi Moore and Jennifer Meyer, to name just a few.

And while Jen was fine to have her exes and their exes/current partners attend, her one and only rule was that there was to be absolutely ZERO ‘gramming of the event, but it looks like Gwyneth and Kate must’ve missed (or ignored) the memo ‘coz check this out:

“Happy birthday (last night and tomorrow) to #jenniferaniston our ray of sunshine, example of perpetual goodness,” Paltrow captioned her post. “We love you so much and you make 50 LOOK.”

“Love these ladies,” Hudson wrote. “Celebrated this beauty last night Happy Bday JA! We all love you sooo!”

Fellow party-guest Katy Perry called Kate out for breaking Jen’s golden rule, writing “NO SOCIAL MEDIA” in the comments section of the post.

The Almost Famous star confirmed that she had gotten “permish” for the upload, presumably via Aniston herself.
