Jennifer Lopez and Ben Affleck 'planned' their divorce and went 'through all the details' BEFORE singer officially filed

Jennifer Lopez and Ben Affleck had 'planned' their divorce before the singer officially filed earlier this week on Tuesday on their second wedding anniversary.

The Atlas actress, 55 - who will attend the premiere of their film Unstoppable without the Oscar winner, 52 - filed for divorce without an attorney and a prenup following only two years of marriage.

However, a source told Us Weekly in an article published on Friday that the estranged couple had previously 'gone through all the details' of their split.

'They had already agreed to these terms before she filed,' the insider continued to the outlet.

Jennifer, 'finally pulled the trigger because that was their agreement that she would file, and she was the one who ultimately made the decision.'

A financial issue in regards to their separation is the pair's lavish $60 million Beverly Hills mansion that was purchased last year. 

Following renovations in the spacious property, the home was listed on the market in July for $68 million. 

The source explained, 'There's really nothing else to divide. One person doesn't want more than the other. They both came in with significant assets of their own.'

Lopez cited 'irreconcilable differences' in her petition for divorce - which also includes a request he does not receive spousal support on top of his estimated $150 million net worth.
