Alison Brie is officially making an honest man out of Dave Franco. The actress stepped out for a Los Angeles screening of her new film "Sleeping With Other People" with a gaggle of girlfriends on Monday (August 24), sporting an impressive piece of new jewelry:

E! later confirmed that the low-key couple -- who have been dating since 2012 -- are engaged, though in this case the rock basically speaks for itself.

Congrats to the happy couple, and the many fortunate cats they will probably adopt!
