Jennifer Aniston threw an epic bash to celebrate her 50th birthday, and the guest list was full to the brim of her A lister buddies.
The star-studded guest list included 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 and Demi Moore, and others!
But it was Jen's ex-husband Brad Pitt attending the lavish party that had fans most excited.
While it was said that the party was quite big...
Apparently there was one golden rule that was not to be broken. That rule was no photo evidence on anyone's social media. But, it seemed that Gwyneth Paltrow and Kate Hudson forgot the #1 rule and both posted photobooth pics on their Instagrams.
Pop star Katy Perry quickly jumped in to the comment section on the A-List actress' posts and told them off, saying: "NO SOCIAL MEDIA"
But luckily it seemed the two rule-breakers had prior permission from the birthday girl herself.
Katy Perry is well known for jumping the comment section of her friend's Instagram's and giving them a hard time. Recently the singer commented on Charlie Puth's Instagram calling him out for saying he never goes to parties even though he sings about them.
