People reported on Rossum's departure. The actor announced via Facebook she would be leaving the show.
“Until ‘Shameless’ came into my life 8 years ago, I led that kind of transient wonderful life of an actor. And I never realized how much I actually craved the kind of continuity that this show has given me. And given all of us in the crew. Season after season I’m amazed that our same crew comes back. And it’s not just because it’s a wonderfully written, wonderfully layered show. There are these real connections, real friendships that bring us back season after season after season,” she added. “See, in real life, unlike Fiona, I’m an only child. I never had a big family. Being ensconced in that messy Gallagher family love is something I’d always dreamed of. But even off set, it feels real. We’ve watched the kids grow up into the strong, talented, independent human beings that they are.”
“I know you will continue on without me, for now,” she concluded. “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.”
