Matt Damon has no qualms about kissing and telling.

The movie star dished on one of his most hellish kissing scene experiences during a press appearance on LADbible with his Oppenheimer co-star Emily Blunt .

The two were discussing etiquette for intimate scenes, when Damon talked about a time he had to kiss Scarlett Johansson in the 2011 film We Bought a Zoo.

Could you imagine how horrible that was for me? Damon quipped, joking that the experience was hell.
