Among the many reasons shared, Handler’s repeated acts of talking about Aniston in the press were said to be quite off-putting for the actress.

The report also suggested that Handler was “jealous” of Aniston, who was already a “big name,” while she was trying “to do anything to be a star.”

Aniston and Handler were once thick as thieves, as evidenced by past photos of them giggling together at award shows and showering each other with praise in interviews.

However, their once-close friendship now seems to have faded, despite Handler previously denying any fallout between them.

A source has now confirmed that Aniston and Handler are no longer close for a number of reasons.

“Jen wants to be more private, while Chelsea wants to be front and center, so perhaps a breakdown was always inevitable,” the insider told the Daily Mail about the duo who became good friends after Aniston made an appearance on Handler’s show, “Chelsea Lately.”

The source further shared, “They jumped into their friendship headfirst and went from not knowing each other to being together 24/7.”

Diving deeper into Aniston’s desire for privacy, the source revealed that it was Handler’s tendency to overshare that ultimately caused their falling out.

According to the insider, the talk show host had a habit of publicly discussing private aspects of Aniston’s life, including taking jabs at Angelina Jolie, who was rumored to have had an affair with Brad Pitt while he was still married to Aniston.

While Handler might have thought she was standing up for her friend, Aniston reportedly felt uncomfortable as she wanted to move on from the drama rather than be dragged back into it.

As time went on and Aniston married her second husband, filmmaker Justin Theroux, her discomfort increased as Handler continued to mention Jolie even though she had long since moved on.

Making matters worse, Theroux was rumored to dislike Handler and her relationship with the “Friends” star. He reportedly found Handler “rude and obnoxious” and disapproved of how she encouraged Aniston to act like she was single.

Things came to a head when Aniston’s marriage to Theroux broke down in 2017.

The actress became increasingly “paranoid” that details of their split would be leaked to the press, and Handler seemed like the most likely culprit who would do so.

“Jennifer became paranoid, thinking that people around her were leaking stories to the press,” the insider revealed. “Chelsea was still talking about Jennifer in interviews, and Jennifer automatically pointed the finger at her.”

From then on, the duo’s relationship became a more distant situation.

While Aniston is still quick to like Handler’s Instagram posts, the comedian is noticeably absent from the group of friends the actress often features in her Instagram snaps.

According to the source, whatever they have now is “not the same as it was, and it will never be.”

They also claimed that during the time they were close, it didn’t help that Handler seemed to be jealous of Aniston’s success.

“Chelsea seemed willing to do anything to be a star, and Jennifer was already a big name, so of course, there were hints of jealousy,” the insider continued.

Since splitting from Theroux, Aniston has kept a low profile regarding her romantic life. However, she was recently linked to actor Pedro Pascal after they were spotted enjoying a three-hour dinner date.

Unfortunately for fans hoping for a romance, the two are just close friends, as Pascal himself has denied being romantically involved with the “Horrible Bosses” star.

“Jennifer and I are very good friends,” he told Entertainment Tonight while attending the season two premiere of his HBO show, “The Last of Us.” “I got to have dinner [with her] on Saturday, and it was a fun martini dinner.”

He also told E! News that they were joined by “mutual friends,” further squashing rumors about the outing being a romantic dinner date.
