Bush will play Vanessa Stanhope, a well-known radio host who spars with Alex (Zach Braff), who left his radio job to start a podcasting company.
Bush left Chicago P.D. last year, reportedly due in part to her co-star Jason Beghe's inappropriate behavior. Since then she's appeared in a couple of movies and signed a deal with 20th Century Fox TV to develop content, which should hopefully be bearing fruit in the form of a pilot pickup soon.
Bush isn't the only familiar face who'll be appearing on Alex, Inc. -- Veep's Matt Walsh will also guest star. He'll be playing Detective Phipps, who has valuable information about an unsolved case that's been a thorn in the side for Rooni (Tiya Sircar), Alex's attorney wife. Walsh is a guest star extraordinaire, having appeared on numerous comedy series, most recently on Crazy Ex-Girlfriend, black-ish and Teachers.
ABC also released key art for Alex, Inc., which TV Guide can share exclusively.
Alex, Inc. premieres Wednesday, March 28 at 8:30/7:30c on ABC.
