There might be a difference of desire in the Megan Fox-Brian Austin Green split.

On Tuesday, E! News reported that after Fox filed divorce papers, Green has responded by citing irreconcilable differences for the reason of the divorce. The actor apparently has made his claim similar to Fox's paper filing in each category, one of them including joint custody of their two children.

One thing that makes a difference is that Green is looking for spousal support while it seems that Fox did not since her part on that was left blank. The site mentioned that usually when it comes to reports like these, the petitioner would check off this box to "terminate the court's ability to award support" for the ex-partner.

This might leave a little suspicion on what went down between these two and why Green marked this, but not Fox.

The former pair are parents to their two sons, Noah, 3, and Bodhi, 1. Green also has a son, Kassius, 13, from a previous relationship.

Fox opened up on her relationship with Green in an interview with Marie Claire U.K. back in 2013.

"I believe he's my soul mate," the actress said. "But that doesn't mean it doesn't take work because we are very, very different."

The two have been married for five years. The announcement of their separation came last August.
