"I don't love planning," Mara confessed to Fallon. "I like planning in my life in general, but wedding planning, I'm just not that interested. Like, ‘What kind of spoon do you want on the table?’ I’m just so uninterested, but Jamie is very interested."
"I will say, 'I don't care', and he will immediately give a response of exactly the color and the shape — well the shape is obvious," she continued before jokingly referring to Bell as "the bride."
Mara, whose family owns the New York Giants and the Pittsburgh Steelers, also revealed that Bell studied up on American football, when they first started dating.
"He learned all about the Giants for me," she recalled. "He spent a night and had his friends come over and watch an entire season of the New York Giants. He knows more about it than I do."
