Megan Fox Files for Divorce From Brian Austin Green

It's official.

It's official -- Megan Fox and Brian Austin Green are headed for divorce.

News broke on Wednesday that the 29-year-old Teenage Mutant Ninja Turtles actress and the 42-year-old former Beverly Hills, 90210 star have called it quits after five years of marriage, but Megan officially filed the divorce papers on Friday.

Fox cites "irreconcilable differences" as the cause of the split, and is asking for joint physical and legal custody over their two sons, 2-year-old Noah and 1-year-old Bodhi.

The divorce is "very amicable" according to TMZ, as the two are still living in the same house. TMZ also cites a source that says there was no prenup between the former couple, meaning that their earnings during their marriage will most likely be divided in half.

The date of separation is listed as June 15, though Megan and Brian haven't been seen at a public event together since Dec. 2014, when they attended the Night of Generosity Gala to support clean water in developing countries. However, they were photographed this past June having lunch together in Beverly Hills, California.

The two had been a couple for 11 years before their surprising split, tying the knot in Maui in June 2010. But their relationship has had its fair share of drama, with Megan previously calling off her three-year engagement to the actor in February 2009, after Green proposed in 2006. He re-proposed to Megan again in 2010, less than a month before they got married in Hawaii. They first met in 2004, when they both appeared on an episode of ABC's sitcom Hope & Faith.

When ET caught up with Megan at the Teenage Mutant Ninja Turtles premiere last August, she joked about their lack of a sex life due to their children and her busy career. Brian also has a 13-year-old son, Kassius, from a previous relationship with actress Vanessa Marcil.

"Brian doesn't get any intimacy whatsoever," Megan joked.
