Firstly, we all know Jennifer Aniston was Brad Pitts's ex-wife and secondly, as this cute, kind, and loving person who would perhaps give her life to her best friends; just like her nearly missed out-character from Friends; Rachel Green.  In fact, many people wanted to be friends or work with her after the well-known show ended in 2004. However, not all is what it seems, because we have found out from several sources that some people hated working with Jennifer Aniston.

Being an A-list star, Aniston has shown quite an attitude on set with her co-stars.

A Diva In Disguise

According to RadarOnline, the 51-year-old actress portrayed herself as an unapproachable individual. A source told the American gossip website that when everyone would eat lunch in the cafeteria facility, the Just Go With It star would grab her lunch as a to-go and leave.

Additionally, her private trailer would be miles away from the film set and the crew members couldn't help but label her as a Diva.

"Her behavior is a clear indicator to everyone that she's not approachable. And it's just unnecessary," Said the source. "There's no reason why she has to act any better than anyone else on that movie set."

Passive-Aggressive Behavior

Aniston had also gone through a phase of showing her passive-aggressive side and thanks to Jay Mohr, we found out his most awkward interaction with a 'female celebrity.' In a recent interview, Mohr said that the 'leading woman' (allegedly, Aniston as the only film he did in 1997 was Picture Perfect and the timeline fit perfectly well) was unhappy with Mohr's presence and had made it clear since day one.

At the time, Mohr wasn't famous but somehow landed the role as the leading character. The actress which he went on to say would often yell, "No way! You've got to be kidding me!" between takes to other actors on set. Mohr was so hurt that he would literally go to his mom's house and cry. However, when asked if it was really Aniston he was talking about, he stated that he would never, ever answer that.

But it's not so hard to guess that it's Aniston, considering the fact that she had been struggling with being a control freak her entire life.

In Charge Of Her Life

The tell the truth, Aniston herself acknowledges that she's a control freak. In an interview with Hollywood Reporter, the Murder Mystery actress stated that she likes to be in charge of everything in her life as she was 'so out of control while growing up.' She would have a hard time with some bad directors, but she would always control herself by biting her tongue and obliging to their orders.

"Some directors are just like -- oh, God, oh God, oh God! I [have to] just suffer through this." She said.

Feud With Other Celebrities

Apparently, several other celebrities such as the late Joan Rivers, Piers Morgan, Elisabetta Canalis, John Mayers, and Kristen Stewart had all either dissed Aniston or said some really impertinent comments.

In 2016, Piers Morgan said a thing or two about Aniston after she had participated in a live Q&A at the Giffoni Film Festival in Italy. NickiSwift reported that Morgan claimed Aniston was self-wallowing and needed to get a grip.

"If you do that, you can't then go, 'Oh woe is me, and they're all taking pictures of my body that I've just put naked on a magazine cover for the 5,000th time. Come on! Get a grip!" Morgan said despite his co-host, Susanna Reid attempting to interrupt and defend the Friends actress.

In 2010, Actress Joan Collins stated to Daily Mail that Jennifer Aniston "is cute, but she couldn't call her beautiful as she's no Ava Gardner or Lana Turner." Then in 2011, comedian Joan Rivers said in an interview with Us Weekly that "she would like to take Jennifer Aniston and put her hair over her f******g face."

It seems there are a lot more celebrities out there as well who haven't come out about Aniston, but can we stop for a moment and consider the fact that Aniston is just another human being with quirks and flaws like the rest of us?
