The movie is an adaptation of Jenny Han's best-selling novel of the same name, Variety reports.
She will star alongside actress Lana Condor (X-Men: Apocalypse) and Anna Cathcart (Descendants 2).
The flick is about a girl who writes love letters to all her past baes but never sends them.
Then one day the letters are *accidentally* sent to each dude and all hell breaks loose.
OoOoOoOo, sounds juicy!
