It should come as no surprise that Megan Mullally has signed on to reprise her role as Tammy on Parks and Recreation next season.

She was hilarious on the 11/5/2009 episode of the sitcom, "Ron and Tammy." Oh, and she's married to the actor that plays Ron Swanson, Nick Offerman.

What might be in store for this onscreen pair of exes when Tammy returns? There's “going to be more fireworks," Mullally told Entertainment Weekly. "What I’ve heard so far is extremely high stakes.”

As previously reported, in other Parks casting news: Mullally’s Party Down costar Adam Scott will come aboard the NBC show in regular role later this season.
