Brad Pitt spotted at ex-wife Jennifer Aniston’s 50th birthday

In a surprise move that turned just about every head in Hollywood, Brad Pitt stopped by his ex-wife Jennifer Aniston's 50th birthday party in Los Angeles Saturday evening. However, Pitt was spotted arriving at the party wearing a flat cap, making it hard to make out if it was him. He did not appear in any of the more official photos that stars posted the following day, although other exes in his and Aniston's entangled Hollywood love lives did.

Aniston also apparently didn't spend a lot of time with him, opting to hang out with her gal pals Gwyneth Paltrow and Kate Hudson instead.

"Love these ladies", Hudson wrote. Happy Bday JA! We all love you sooo!'

We chose to look back at Jen's transformation through the years to mark her 50th birthday. "We love you so much and you make 50 LOOK [fire emoji]". Katy Perry, Courteney Cox, Sara Foster, Orlando Bloom, and others are featured in the photos.

Aniston married actor Justin Theroux in August 2015 after becoming engaged in 2012. Cox's ex-husband, David Arquette also showed up.

A source tells ET that Pitt "wanted to support" Aniston because the former couple have "been friendly" in the years following their split.

Brad and Jennifer were married for five years, from 2000 to 2005, before they parted ways following Brad's relationship with Angelina. However, it turns out that fans should not get their hopes up!

"For well over a decade now they have lived totally separate lives and so not surprisingly, they have become totally different people than who they once were when they were together", said the source.

However, a source said: "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".
