Jennifer Aniston hosted a tree managing party on Saturday; which was gone to by a few A-listed actors, including her ex Brad Pitt.

“The annual tree trimming party is always Jen’s favorite to host,” the source says. “She loves Christmas. As usual, a large group of friends attended.”

Regarding Pitt’s appearance, the source adds, “They have been in touch a few times since her birthday and are keeping it friendly.”

Back in February, the Ad Astra star, 55, additionally went to Aniston’s 50th birthday celebration party, which was held at the Sunset Tower Hotel in L.A.

“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.”

“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.”

Pitt has also brushed off any notion of reconciliation. In a video shared by Entertainment Tonight in May, Pitt laughed when a paparazzo asked him the one question “everyone wants to know”: is he getting back with Aniston?

“Oh my God,” Pitt said, before hopping in his car and telling the shutterbug, “Alright, have a good one.”
