Jennifer Aniston celebrated her 50th birthday on Saturday night with a star-studded bash that was attended by an array of celebrities — including the “Friends” star’s ex-husband Brad Pitt.
According to People and other sources, the “World War Z” star was seen arriving at the party, held at the Sunset Tower Hotel in Los Angeles on Saturday, Feb. 9.

Other stars in attendance included Pitt’s former fiancee Gwyneth Paltrow, Aniston’s ex-boyfriend John Mayer, his ex Katy Perry and her current boyfriend Orlando Bloom (who arrived together on a motorcycle), along with George and Amal Clooney, Barbra Streisand, Jason Bateman, Robert Downey Jr., Ellen DeGeneres, Kate Hudson, Laura Dern, Demi Moore, Aniston’s formers “Friends” co-star Lisa Kudrow and Reese Witherspoon.



Following the soiree, a source told People that Aniston was “very happy” that Pitt was there to help celebrate this milestone in her life.
“Basically, every single person who Jen loves attended. That included Brad,” the source said. “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,” continued the source. “She was very happy that he showed up. Many of his close friends were at the party too.”
However, the source poured cold water on those persistent tabloid rumours of a rekindled romance, reporting that Aniston “didn’t really pay any special attention to Brad,” adding: “They hugged and chatted for a bit, but Jen was busy making sure all of her other guests had an amazing time.”
