On September 19, Angelina Jolie filed to divorce Brad Pitt.

On September 15, it has been alleged that Pitt berated 15-year old son Maddox aboard a private airplane, leading to an FBI investigation over whether or not he physically abused his son as well.

However, according to a new bombshell report, Jolie and Pitt started to have problems long before either of these incidents.

In fact, the marriage between these stars has been over for years.

We just didn’t know it until now.

While much has been made over the Pitt versus Maddox confrontation – and while a number of sources have claimed Pitt’s drug use and poor parenting are to blame for the couple’s split – an insider says something different to Radar Online.

This mole claims that the romance basically ended in early 2014 after Jolie and Pitt got into a heated exchange at the Academy Awards.

“She behaved so badly that night, trying to steal all the attention from him,” Radar writes of the ceremony.

Pitt was featured prominently at the Oscars that years due to his role in the frequently-nominated 12 Years a Slave.

And Jolie allegedly responded with jealousy and pettiness, trying to upstage her husband via a revealing dress and obnoxious behavior.

“She was so awful to him [that] his Plan B team that he cut short his own celebration with the 12 Years A Slave co-stars,” claims this insider, adding:

“She wouldn’t let him enjoy the win for even a second.”

Jolie truly rose to stardom back in 2000 when she won the Academy Award for Best Supporting Actress for her role in Girl, Interrupted.

But we guess that victory wasn’t enough.

Instead of being happy that the supposed love of her life had starred in such a well-reviewed and decorated film, she apparently could not handle Pitt’s success back then.

According to the source, Jolie’s awful behavior at the time “marked months of her eye rolling and getting jealous and bored of Brad and Plan B dominating everything in the lead-up to the Oscars.”

As a result: “They had a massive fight that night and agreed to split,” Radar claims.

We know what you’re thinking:

Wait… didn’t Pitt and Jolie actually get married in 2014?!?

They sure did, in August of that year.

But Radar essentially compares this decision to when troubled couple have a baby, thinking that it will help them move past their problems.

The site writes that “the wedding was an attempt to patch up the damage that had began during the awards season earlier that year.”

Did it work? Maybe, for a little while at least.

But it was mostly a case of too little, too late.

Which is now to say that an unfortunate exchange between Pitt and Maddox didn’t take place on board that airplane. It did. A rep for Pitt has confirmed as much.

But it sounds as if this incident only really gave Jolie an excuse to finally, officially, legally end the famous union.

In reality, Brangelina had already been over for a very long time.
