Some celeb couples have been in the public eye for years. Parker and Broderick. Z and Knowles. Hawn and Russell. Ok not married, but have been together for so long, it's almost a given.

So when The Huffington Post featured celeb couples you probably didn't know were together, well I was actually interested. And read the whole article. AND was even driven to a few "really...?" statements. Like these couples.

Megan Mullally and Nick Offerman ("Parks & Recreation")

Offerman and Mullally play crazy exes Ron and Tammy on "Parks and Recreation," where Ron often describes Tammy as a "serious b**ch" whom he hates with a passion. But in real life, the couple has been married since September 2003.

And

Rob McElhenney and Kaitlin Olson ("Always Sunny In Philadelphia")

Mac and Sweet Dee definitely don't get along on "Always Sunny," but the actors who play them -- Rob McElhenney and Kaitlin Olson -- have been married since September 2008. Yes, that means she stuck with him even during the "fat Mac" stage.

And the one that surprised me the most.

Cobie Smulders and Taran Killam ("How I Met Your Mother")

On "How I Met Your Mother," Cobie Smulders played news anchor Robin Scherbatsky for nine seasons while Taran Killam played Gary Blauman -- the guy known for yelling back at his boss -- for just a handful of episodes. While their story lines didn't really connect, the actors themselves did; they got married in September 2012.

The guy from SNL? Isn't he like 24? And isnt she 44? Not there's anything wrong with that...still.
