Mark-Paul Gosselaar and Catriona McGinn are still planning their wedding. But they know one thing: It’s not going to be small.
“Once we find a place where we want to have it, then we’ll set a date. But it’ll be a grand event. A lot of family,” the actor, 37, tells PEOPLE.
The Franklin & Bash and former Saved by the Bell star says they’re not leaning toward having a theme, but they do want to make it “a family affair.”
