Brad Pitt shows up at ex Jennifer Aniston's birthday party

A surprise show was ex-husband Brad Pitt, confirming more than a decade of rumours that the pair remained close friends following the break down of their marriage in 2005.

Gwyneth Paltrow, who was engaged to Pitt until 1997, was also spotted at the bash, as well as Aniston's former castmates Courteney Cox, Lisa Kudrow and Cox's ex-husband, David Arquette.

Jennifer Aniston was born February 11, 1969.

"He came to support her, spoke to other friends of his that were there and headed out", the insider said.

The actress, who is celebrating her 50th birthday, held a party on Saturday night at the Sunset Tower Hotel in Los Angeles, and it seemed like everyone (besides us) was there.

Then Pitt met Angelina Jolie on the set of Mr & Mrs Smith in 2003, ditched Aniston, had six kids and decamped to a French chateau with the actor-turned-humanitarian. Aniston and Pitt both recently divorced their second spouses.

"Jen was the first guest to arrive around 8 p.m. wearing a black jumpsuit with her hair down", a source tells E!

The sweet gesture comes after Theroux missed Aniston's milestone birthday party over the weekend, instead attending the Opening Ceremony Lunar New Year 2019 celebration for New York Fashion Week on Sunday.

Besides her very public personal life, Aniston is best known for her breakout role on the TV show "Friends", where she starred as Rachel Green on the late-90s/ early 2000s sitcom.

Could Pitt showing up to Aniston's party be a sign of a rekindled romance?

"In an effort to reduce any further speculation, we have chose to announce our separation", they said in the statement in February 2018. "We are two best friends who have made a decision to part ways as a couple, but look forward to continuing our cherished friendship", they said when they confirmed their separation.
