Scarlett Johansson jokes her husband's movie cameo was down to prenup

The actress is currently promoting new romantic comedy Fly Me to the Moon and attended the premiere for the movie in New York City on Monday evening alongside spouse Colin Jost. Scarlett, who also co-produced the film, quipped that she insisted Colin appeared in the project because director Greg Berlanti is a big fan of the comedic writer and actor. Scarlett explained to Jimmy Fallon during an appearance on The Tonight Show on Monday. "Greg is a huge fan (of Colin). And Colin's, like, I think he had to do it because it's like in our prenuptial agreement. If I have to do something, he has to be there to support me."
