Hudson will play the role of Veronica Moore, a Tony Award-winning Broadway star who affects the lives of Karen (played by Katharine McPhee) and Ivy (played by Megan Hilty).
NBC Entertainment Chairman Robert Greenblatt, who made the announcement, said Hudson's character "will represent someone who reached their Broadway dream but also paid a price for it."
In addition to her stint on the upcoming second season of "Smash," Hudson also has two films, "Lullaby" and "The Inevitable Defeat of Mister and Pete," going into production this summer.
