Back in February, theAd Astrastar, 55, alsoattended Aniston’s 50th birthday party, which was held at the Sunset Tower Hotel in L.A.
An insidertold PEOPLEat the time that his appearance came simply because the former couple, who were married from 2000 to 2005, has a “very civil relationship.”
“He would not have been asked to come if that weren’t the case. It was a big night for Jen,” the insider said. “The important people in her life gathered to celebrate with her. Brad fits into that group, and it was natural that he would want to come.”

After Aniston and Theroux’s divorce, a sourcetold PEOPLEthat reconciliation between Pitt and the actress was highly unlikely.
“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,” the source said. “They’ve been over each other for longer than they were ever together. It is such ancient history.”
“Oh my God,” Pitt said, before hopping in his car and telling the shutterbug, “Alright, have a good one.”
