Alison Brie and Dave Franco have been dating almost two years! The 'Community' actress recently tweeted in support of boyfriend Franco, and his famous brother James Franco who is starring in "Of Mice And Men" On Broadway. Amanda Peet and Natasha Lyonne have joined the cast of "Sleeping with Other People," which Brie will star in.

"Backstage photo - last nite w/@Sethrogen @ZacEfron@alisonbrie @MintzPlasse @JamesFrancoTV and more!," tweeted Brie. "Loved seeing "Of Mice and Men" last night, starring @JamesFrancoTV. Truly wonderful performances by all. @miceandmenbway."

Brie even retweeted a tweet promoting Franco's movie "Neighbors" and its release date.

"In two weeks, things get hardcore. #NeighborsMovie in theaters on May 9," retweeted Brie.

Brie's new movie, "Sleeping With Other People," just added a few people to its cast. Amanda Peet, Jason Mantzoukas, and Natasha Lyonne are joining the cast of Sleeping With Other People, Sidney Kimmel's romantic comedy. The film is written and directed by Leslye Headland, who wrote the hilarious 2012 movie "Bachelorette," according to the Hollywood Reporter.

The cast of "Sleeping With Other People" already includes Jason Sudeikis, Alison Brie, and Adam Scott (Parks and Recreation, Bachelorette).

SKE is financing the comedy, which will shoot in New York in June. SKE describes the project as an "edgy romantic comedy about a womanizer named Jake (Sudeikis) and a serial cheater (Brie) who form a platonic relationship to overcome their chronic infidelity in this witty, contemporary take on modern dating -- in the vein of When Harry Met Sally ... but with assholes."

Amanda Peet most recently appeared in The Way Way Back alongside Steve Carell and Toni Collette for Fox Searchlight.

Mantzoukas, who stars on the hit FX comedy The League, can be seen in the Seth Rogen-Zac Efron hit 'Neighbors,' with Alison Brie's boyfriend Dave Franco.

Natasha Lyonne currently stars in the critically acclaimed Netflix original series Orange Is the New Black.
