"Teenage Mutant Ninja Turtles" star Megan Fox has officially filed for divorce with Brian Austin Green, and the actress wants joint custody of their two kids.

In filing the divorce, Megan Fox cited "irreconcilable differences" as the reason.

"Sources close to the couple tell TMZ, there is no prenup, so earnings during their 5-year marriage are community property and divided 50/50. They've been together for 11 years and we're told the probability is their assets are so co-mingled, they will be divided in half," the article said.

With the divorce filing, Megan Fox seems to be on the losing end as she's expected to pay Brian Austin Green spousal support, "partly because of the disparity in income and partly because he's had medical problems."

The former couple is also reportedly living in the same house for the meantime, which speaks of how smooth the divorce proceedings were.

People magazine reported that Megan Fox and Brian Austin Green just moved in different directions in terms of their careers and personal lives.

The source told the magazine, "Megan is young and hot and sought after for work, and she is eager to move ahead in her career. Brian wants more of her time than she can allow."

Megan Fox also reportedly felt pressured with balancing her career, being a mother and being a wife to an allegedly demanding Brian Austin Green.

The insider alleged, "She was overwhelmed with the children and her husband's expectations, which got in the way of work responsibilities. They had many disagreements and arguments about her time at home, which led to problems."

But another source told People that the divorce was prompted by Megan Fox shifting priorities.

"Megan has always been career-oriented and noted because she was so beautiful. Now she is being recognized for her talent, and like anyone else with Hollywood ambitions, she wants to pursue those options. The timing just wasn't working for her relationship," the source added.
