'Portlandia' Season 4 Has Some Amazing Guest Stars, But Who Will They Play?

Portlandia's coming back for its fourth season on Feb. 27, and they just announced the slew of celebrities, comedians and musicians that will be guests on Porlandia next year. Of course, Kyle MacLachlan will be returning to the sketch show as Portland's seemingly permanent mayor, as will previous guest stars Steve Buscemi, Annie Clark (aka St. Vincent), Jeff Goldblum, Kumail Nanjiani, Ed Begley Jr., Gus Van Sant, and Jason Sudeikis. Season 4 has a weird and diverse mix of guests, including jazz duo Tuck and Patti, Silas Weir Mitchell from Grimm, comedian Nick Swardson, Joshua Homme from Queens of the Stone Age, Duff McKagan from Guns 'n Roses, Mark Proksch from The Office, Michael Nesmith from The Monkees, Microsoft co-founder Paul Allen, and members of the Portland Trail Blazers basketball team.

But the question is, just who will they play? Who will shake things up with Peter and Nance or be unlucky enough to walk into the Feminist Bookstore? Let's play the Speculation Game...

Kirsten Dunst

Who: The blonde waif of an actress who starred in Spider-Man and Melancholia

What she could be: If this were Season 3, Dunst could totally play the Chloe Sevigny role of Fred and Carrie's shared girlfriend. But since this is Season 4, I really hope she'll appear as a Lipstick Feminist author who does a book signing at the Feminist Bookstore.

Tunde Adebimpe

Who: Lead singer of TV on the Radio

Speculation Generator says: She'll play musician who makes an album out of field recordings of people's existential breakdowns.

Dan Savage

Who: Sex and love columnist for his syndicated advice column Savage Love.

Speculation Generator says: He'll play someone who's in a non-monogamous relationship with everyone in Portland

Jeff Tweedy

Who: Lead singer of Wilco

Speculation Generator says: He'll play the lead singer of an alt-country band that writes songs about middle-class suburbia

Vanessa Bayer

Who: Saturday Night Live cast member and Miley Cyrus impersonator

Speculation Generator says: She'll play the owner of a cupcake shop with the world's most adorable and most disgusting cupcakes.

Jello Biafra

Who: Former lead singer for the Dead Kennedys and Green Party supporter

Speculation Generator says: He'll play an obnoxious record collector.

Maya Rudolph

Who: Former SNL cast member and Bridesmaids star

Speculation Generator says: She'll play meditation teacher who keeps interrupting her students.

k.d. lang

Who: Your mom's favorite singer-songwriter from the '90s

Speculation Generator says: Something tells me that this might mean a resurrection of the "Dream of the '90s" skit...

Olivia Wilde

Who: Actress in films like Her and Jason Sudeikis' baby mama

Speculation Generator says: A "sexy" animal rights activist who's kind of sexist (yeah that's right, I'm looking at you, PETA).
