Also in attendance was Gwyneth Paltrow, John Mayer, Katy Perry, Orlando Bloom and Kate Hudson.
George and Amal Clooney, Reese Witherspoon, Robert Downey Jr., Ellen DeGeneres, Barbra Streisand, Keith Richards, Laura Dern, Demi Moore and Jennifer Meyer were among the familiar faces at the star-studded event, as were Aniston’s Friends costars and good pals Lisa Kudrow and Courteney Cox.
Pitt and Aniston split in 2005 after five years of marriage. Pitt went on to marry Angelina Jolie and Aniston wed Justin Theroux. Sadly, neither marriage worked out and both Pitt and Aniston are both currently single.
But, don't let your imagination run wild. Per People's source, who alleges to be close to both parties, Pitt and Aniston aren't exactly reconciling.
“They aren’t in regular contact," the source said. "Beyond an occasional text back and forth to wish each other the best when there’s been a new project or big event."
