People still cannot stop gushing over the reunion of one of Hollywood’s most prominent ex-couples, Brad Pitt and Jennifer Aniston. The two got together for a reunion during Aniston’s star-studded 50th birthday party held at Sunset Tower Hotel in Los Angeles.

The meetup of the ex-couple sparked rumors about rekindling their romantic relationship. Fans raved the potential reconciliation of the two over social media. More rumors ignited after reports confirmed that Aniston herself invited Pitt to attend her party.

News claimed that Aniston was more than happy to see Pitt in her 50th birthday celebration. An insider was aware of the rumors flying around about the two and was quick to defend them in an interview with PEOPLE. “Basically, every single person who Jen loves attended,” the insider said. “That included Brad. The party was a celebration of Jen’s life.”

“Brad, for long, was a very important part of Jen’s life,”  the insider went on. “She debated back and forth with friends if she should invite him. She was very happy that he showed up. Many of his close friends were at the party too.”

However, a week after the birthday bash, fans and rumors are still dishing about Aniston and Pitt’s reunion. People became more excited when it was reported that Pitt mailed a gift to Aniston days before the actual celebration. No details were revealed on what gift Pitt gave to Aniston. But sources say it was definitely something special.

However, most who attended Aniston’s party had sent their gifts days ahead of the party too. “Her friends are all very generous and creative, and she seemed very excited by all the gifts,” a source tells PEOPLE.

Both Aniston and Pitt’s side shut down hopes of the two going romantic and cleared that ever since they have been divorced, their relationship remains casual and civil.
