The Shameless star and the writer/director became engaged over the weekend in Los Angeles, PEOPLE has learned exclusively. Rossum, 28, and Esmail, 37, have been dating for two years.
The happy personal news adds to what has been quite a year professionally for the couple, with Rossum’s turn as Fiona on Showtime’s Shameless continuing to earn her acclaim, and Esmail’s work as the creator of USA’s buzzy drama Mr. Robot making it a breakout year for him.
Esmail directed his bride-to-be in his 2014 romantic dramedy Comet, which also starred Justin Long.
