“Basically, every single person who Jen loves attended. That included Brad,” a source tells PEOPLE
“Basically, every single person who Jen loves attended. That included Brad,” the source says. “The party was a celebration of Jen’s life.”
“Brad, for long, was a very important part of Jen’s life. She debated back and forth with friends if she should invite him,” adds the insider. “She was very happy that he showed up. Many of his close friends were at the party too.”
Even though Aniston invited her ex-husband to the bash, she “didn’t really pay any special attention to Brad,” the source explains.
“They hugged and chatted for a bit, but Jen was busy making sure all of her other guests had an amazing time,” the source shares.
PEOPLE previously confirmed that Pitt attended the actress’ birthday party on Saturday, which was held at the Sunset Tower Hotel in Los Angeles.
Photos show the actor arriving at the hotspot with his long hair slicked back underneath a cap, making a casual entrance at the hotel.
A source previously told PEOPLE the party guests at Aniston’s bash also included Pitt’s ex Gwyneth Paltrow, plus Aniston’s ex John Mayer, as well as the musician’s ex Katy Perry, who was joined by boyfriend Orlando Bloom.
George and Amal Clooney, Reese Witherspoon, Robert Downey Jr., Ellen DeGeneres, Barbra Streisand, Keith Richards, Kate Hudson, Laura Dern, Demi Moore and Jennifer Meyer were among the familiar faces at the star-studded fête — as were Aniston’s Friends costars and good pals Lisa Kudrow and Courteney Cox.
The following day, a handful of Aniston’s pals began wishing the star a happy birthday on social media, sharing their own sweet images taken from the celebration.
“Love these ladies,” Hudson wrote alongside a series of photo booth GIFs on Instagram, in which she posed alongside Aniston and Paltrow. “Celebrated this beauty last night ✨Happy Bday JA! We all love you sooo!”
Hinting that there had been a ban on sharing images for the bash, the “Chained to the Rhythm” singer commented on the image, writing, “NO SOCIAL MEDIA.”
In her own post, Paltrow wrote, “Happy birthday (last night and tomorrow) to #jenniferaniston our ray of sunshine, example of perpetual goodness. We love you so much and you make 50 LOOK 🔥.”
Following the news of Aniston and ex-husband Justin Theroux‘s split in February 2018, a source with knowledge of Pitt and Aniston’s relationship told PEOPLE the stars — who were married from 2000 to 2005 — had “been over each other for longer than they were ever together.”
While Aniston and Pitt had remained friendly over the years, the source said the two weren’t especially close. “They aren’t in regular contact, beyond an occasional text back and forth to wish each other the best when there’s been a new project or big event,” the insider said at the time.

Opening up about her personal life in the January 2019 issue of Elle, Aniston shared that even though her relationships with Pitt and Theroux didn’t last, knowing when to end a relationship has its own value.
“I don’t feel a void. I really don’t,” the Dumplin’ star explained. “My marriages, they’ve been very successful, in [my] personal opinion. And when they came to an end, it was a choice that was made because we chose to be happy, and sometimes happiness doesn’t exist within that arrangement anymore.”
“Sure, there were bumps, and not every moment felt fantastic, obviously, but at the end of it, this is our one life and I would not stay in a situation out of fear. Fear of being alone. Fear of not being able to survive. To stay in a marriage based on fear feels like you’re doing your one life a disservice,” she added. “When the work has been put in and it doesn’t seem that there’s an option of it working, that’s okay. That’s not a failure. We have these clichés around all of this that need to be reworked and retooled, you know? Because it’s very narrow-minded thinking.”
