Brad Pitt was spotted at Jennifer Aniston’s star-studded 50th birthday bash. A source told People magazine that “every single person who Jen loves attended” and she wanted the party to be a celebration of her life.

She had “debated back and forth with friends” if she should invite Pitt and she was so happy when he accepted her invitation.

Brad showed up with his long hair slicked back underneath a hat and made a casual entrance. He and Jennifer hugged and chatted for a while, however she couldn’t spend too much personal time with her ex-husband as there were many other guests that she had to attend to.

The Pitt-Aniston divorce had shocked many people in 2005, and was sealed when Pitt entered a long-term relationship with Angelina Jolie. Aniston and Pitt had remained friendly but weren’t especially close.

Other guests included George and Amal Clooney, Reese Witherspoon, Ellen DeGeneres, Barbra Streisand, Kate Hudson, Demi Moore, Gwyneth Paltrow, Katy Perry, Orlando Bloom and another of Jennifer’s exes, John Mayer.

The party took place at the Sunset Tower Hotel in Los Angeles.
