"Playing Fiona Gallagher has been one of the great privileges of my life," she wrote on Twitter. "I'm so happy to continue w my SHAMELESS family! Back to work in May!"
It appears the actress was able to settle her wage dispute after demanding equal pay and possibly more money than her co-star, William H. Macy, citing she has more screen time than the Oscar-nominated actor.
According to Variety, Rossum was offered pay equality earlier this year, but held out in an effort to negotiate a higher salary. ET has reached out to Showtime and Rossum's rep for comment.
In an interview with TMZ on Tuesday, Macy expressed his support to Rossum, stating, "They wrote the Equal Rights Amendment in 1927, it didn’t get passed until 1972. It still hasn’t been approved by all the states, therefore is didn't make it as an Amendment to the Constitution. It’s about f**king time, don’t you think?”
"She works as hard as I do, she deserves everything," he added.
Shameless, along with Homeland, ranks as Showtime's longest-running scripted original series and most watched.
