Shahi will guest star as Renee, a love interest for firefighter Kelly Severeid (played by Taylor Kinney). Shahi has already started shooting the role, and although there's no airdate yet, viewers may get to see her on screen by the end of the year.
Shahi has played mediator Kate Reed for two seasons of Fairly Legal on USA. The cable network has not yet decided on whether the show will be back for another season. Shahi, who was just named "TV's sexiest star" by Maxim magazine, has also been seen in The L Word and Life.
NBC recently picked up five more scripts of Chicago Fire.
