It went something like this: Liz: So, do you like cheese? Britt: Yeah, who doesn't like cheese? Liz: Well... would you maybe like to have cheese and wine (with me) some time? Britt: Are you asking me on a cheese date? It's obvious we brie-long together, and that’s how it all started.

Liz proposed in St. Stephen's Green in Dublin, Ireland. They spent the day in cheese and wine shops and left a lock on Ha'Penny Bridge. They ended the day in a bar called the Long Hall, since, well, they're in it for the long haul!
