Modern Family hasn't lost its touch when it comes to snagging very special guest stars.
In a very rare TV stint, The Social Network star will play Asher, Mitchell and Cam's eco-nut neighbor.
Krakowski, making her first small-screen appearance since 30 Rock's finale, will play Dr. Donna, a mean mother of one of Manny's classmates who ends up going head-to-head with the always feisty Gloria.
Most recently seen on The Good Wife, Hickey will portray a therapist who helps a member of the Dunphy family.
The episode, titled "Under Pressure," starts filming next week and is tentatively scheduled to air early next year.
Modern Family airs Wednesdays at 9/8c on ABC.
