Happy birthday to Jennifer Aniston!

The star turned 50 Monday, but she didn't wait to get the party started. On Saturday, Aniston invited a slew of notable names to join her at the Sunset Tower Hotel in Los Angeles and celebrate.

And as fun-filled photos from the night prove, that's just what they did.

Kate Hudson shared a set of party pics featuring herself, Gwyneth Paltrow and Aniston smiling, drinking and hamming it up for the bash's photo booth.

"Love these ladies," she captioned a clip featuring a collection of shots. "Celebrated this beauty last night. Happy Bday JA! We all love you sooo!"

That sweet post prompted fellow partygoer Katy Perry to respond with a warning: "NO SOCIAL MEDIA."

While that no-share sentiment is a common rule at hush-hush celebrity shindigs, the singer didn't have anything to worry about this time. As Hudson soon explained, she "got permish."

And apparently, she wasn't the only one.

Paltrow shared more shots, as well as a heartfelt message for Aniston, whom she called "our ray of sunshine" and "example of perpetual goodness."

The Goop founder wrote, "We love you so much and you make 50 LOOK (hot)."

The guest list included friends and former co-stars — as well as two former "Friends" co-stars, Courteney Cox and Lisa Kudrow.

Reese Witherspoon was there, as were many guests who didn't pose for the cameras (or if they did, they must have stuck to that "no social media" rule).

George and Amal Clooney, Barbra Streisand, Laura Dern, Ellen DeGeneres, Demi Moore, Robert Downey Jr. and David Arquette were all in attendance.

In fact, according to People, "Basically, every single person who Jen loves attended," which reportedly included ex-husband Brad Pitt.
