Kristen Stewart is thought to be taking on the starring role in the upcoming Christmas themed rom-com, from director Clea DuVall and writing partner Mary Holland.
According to The Hollywood Reporter, 'Happiest Season' follows a young woman whose plan to propose to her girlfriend whilst at her family's annual holiday party is thrown into chaos, when she discovers her partner hasn't yet come out to her conservative parents.
The project will be produced by Temple Hill's Marty Bowen, Isaac Klausner and Jaclyn Huntling. Hannah Minghella and Shary Shirazi will oversee the project for TriStar.
As of the time of writing, it's unknown which of the main characters Kristen will be taking on, and no other casting announcements for the other star have been made.
Kristen herself identifies as bisexual, and as well as previously romancing her 'Twilight' co-star Robert Pattinson, has enjoyed romances with French singer Soko, musician St. Vincent, and is currently dating New Zealand model Stella Maxwell.
