Alexis Denisof on Private Practice

Just last week, it was announced that Alexis Denisof and wife Alyson Hannigan (of How I Met Your Mother) were expecting their first child.

It turns out that's only the tip of the propagating iceberg for Denisof.

TVGuide.com has learned that on the Nov. 19 episode of ABC's Private Practice, the Buffy/Angel alum will guest-star as a father-to-be who comes to Oceanside Wellness with a pregnant wife in tow.

He then returns later, with a second expectant Mrs. in need of Addison's attention. Talk about big love.

I'm not one brazen enough to predict story line outcomes, but… no, this cannot possibly end well.
