In May 2012, Alison Brie and Dave Franco had been dating for at least five or six months, and the couple largely kept their romance outside the spotlight until it was confirmed in August 2015 that they were engaged.
In a February 2016 interview with Yahoo! Dave Franco noticed that marriage never really interested her. However, the actor changed her mind. He said he just met that person that he was like really in love and would like to grow old with that person.
Alison Brie recalled that she actually thinks it’s much more romantic when two people could go either way on marriage, but still wants to marry you. Alison Brie revealed during a June 2017 appearance on Larry King Now that Franco got down on one knee in Big Sur, California.
Alison Brie admitted that she didn’t answer him right away, she recounted that since she was so shocked that she actually burst out laughing and asked him a number of times if he was being serious before saying yes.
