The Fantastic Four co-stars got engaged in January. They've been dating since 2015, shortly after filming their superhero movie.

Last month, 34-year-old Mara revealed Bell was much more interested in wedding planning than she was during her appearance on The Tonight Show Starring Jimmy Fallon.

"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," she continued, jokingly referring to 31-year-old Bell as "the bride."
