Dave Franco opened up about his marriage to Alison Brie – and how he knew she was the one – during The Tonight Show Starring Jimmy Fallon on Thursday, September 21.

Franco, 32, admitted that Brie’s love for cats was a huge plus in their relationship.

“We call them the small panthers. Alison loves them, thank God. She was really my only option.”

Brie threw him an ’80s-themed birthday party, but unfortunately the night didn’t go as planned.

“When we first started dating, my birthday came up three months into the relationship and she decided to throw me a surprise party, which was very sweet. She put a lot of effort into it. But the guest list got a little out of control,” Franco said on Thursday night.

After three years of dating, the couple tied the knot in March, even though Brie previously said she may not be the marrying kind.
