A source close to the two told People, "Megan and Brian have decided to separate. They will always love each other very much and are devoted to their kids. Anything could happen in the future, but for now they've decided it's best to take some time apart."
Megan and Brian have reportedly been living separate lives for several months and haven't been seen together much this year.
Though they have split, they will continue to be in each other's lives, since they share sons Noah Shannon, 2, and Bodhi Ransom, 18 months.
Megan and Brian began dating soon after they met on the set of her show "Hope & Faith" in 2004. They initially got engaged in 2006, but called it off in 2009. They eventually got back together and married in 2010.
