Rossum confirmed the following in a statement.
I know you will continue on without me, for now. There is much more Gallagher story to be told. I will always be rooting for my family. Try not to think of me as gone, just think of me as moving down the block.
Subsequently, Shameless and the cast released the following statement.
“Emmy Rossum will forever be part of the Shameless family. She has been integral to the show’s success, from her wonderful portrayal of Fiona to her leadership role on set, as well as directing multiple episodes of the series. We are hard at work now creating a season nine finale for Shameless which we hope will provide a Gallagher-worthy sendoff for Fiona that honors the great work Emmy has done. It is always bittersweet when an ensemble member decides to move out of the proverbial house, but our door will always remain open for Fiona to return home for a visit, or to move back in. I look forward to continuing the stories of this wildly unpredictable family and all of us on Shamelesswill miss Emmy and her wonderful Fiona.”
