Us Weekly broke the news exclusively early Wednesday, citing sources close to Megan who claim the Jennifer's Body actress initiated the seperation six months ago - in spite of the fact that they were spotted out and about together as recently as June 9th.
Megan and Brian have two children together, 2-year-old Noah and 18-month-old Bodhi.
More details are hard to find and are vague at best. The article in question goes on to say that the romance between the couple "has been plagued with issues" and that "things have been rocky" for an unwritten about amount of time.
29-year-old Fox met the 42-year-old Beverly Hills, 90210 alum when he guest starred on an episode of her ABC sitcom Hope & Faith in 2004. They married in June 2010, despite Megan breaking off their 3-year engagement a year and a half beforehand in February 2009.
