'Mad Men' & 'Big Love' Star Anne Dudek: I'm Getting Divorced with New Age Child Custody Plan

Actress Anne Dudek is divorcing her husband of nearly 8 years, but she's down to try the newest fad in child custody arrangements.

Dudek -- who's had roles on "Mad Men," "Big Love," 'House' and "Covert Affairs" -- has 2 kids, ages 7 and 4, with her soon-to-be ex, Matthew Heller.

According to the docs, Dudek wants to share legal and physical custody, but the physical part is where it gets interesting. Anne wants the kids to stay in one house, while she and Matthew rotate in and out every 3rd day or so.

"Bird nesting" is kinda the "in" thing to do -- and not just in Hollywood -- since psychologists think it's a good way to create stability for children of divorce.
