'Parks and Recreation' books Sean Hayes to interview Leslie

Sean Hayes will help Leslie Knope get her city council campaign back on track on "Parks and Recreation." Maybe.

The former "Will & Grace" star (and executive producer of NBC's "Grimm") will join the "Parks and Rec" crew for an episode set to air in the spring, TVLine reports. He'll play a well-known TV journalist from Indianapolis who interviews Leslie (Amy Poehler) about her campaign.

Leslie, of course, is hoping that she'll get a boost in the polls. We're guessing it might not go down exactly that way.

Hayes is the second "Will & Grace" cast member to appear on "Parks and Rec." His former partner in comedy, Megan Mullally, has made several appearances on the show as Ron's (Nick Offerman) ex-wife Tammy.

Hayes stars as Larry Fine in "The Three Stooges" movie that's due for release in April, and he's also attached to star in a comedy pilot in development at NBC.
