Rarer Than A Smiling Olsen!

Emily Blunt and Office hottie John Krasinski must not have seen the photogs, because the peeking paps managed to snap a photo of the secretive couple together in one shot.

The two spent the day together on Saturday. And then in the evening, they went on a double-date with Blunt’s Devil Wears Prada co-star, Anne Hathaway, and her new bf, Adam Shulman, to tapas restaurant A.O.C.

How cute!
