The New York Post reported that the lovebirds, who met on the set of the series Shameless, went separate ways.
Rossum was seen in the Hamptons this weekend, telling her friends that she was ”single again.”
‘Hope you all had a happy and safe 4th.’
‘Back to work starting tonight on a new film called #curfew in my home state New York,’ she tweeted on Friday.
Unfortunately the reasons which led to the separation aren’t known yet.
