Jennifer Lawrence played Katniss Everdeen in the "Hunger Games" series, while Liam Hemsworth played Gale Hawthorne, one of Katniss’s love interests. With romance subplots come kiss scenes, and while these can be awkward — especially if the actors are friends — Hemsworth had even more of a reason to dislike kissing Lawrence.

Lawrence didn't pay much attention to her breath when she filmed "The Hunger Games." "Whenever I had to kiss Josh [Hutcherson] and Liam [Hemsworth] for 'The Hunger Games,' who cares?" Lawrence said on the "Graham Norton Show" in 2016. I'd eat like mustard and tuna, like, who cares?"

That habit made the experience "awkward," Hemsworth said on "The Tonight Show" in 2014: "If we had a kissing scene, she would make a point of eating garlic or tuna fish or, you know, something that was disgusting," the actor told Fallon. Lawrence apparently wanted to prank her longtime friend just a little.

Later on, however, Lawrence seemingly changed her ways. She recalled how sharing the screen with Christian Bale in "American Hustle" and Chris Pratt in "Passengers" forced her to clean up her act: "I was really clean and mints and mints and mints," she said of her kissing scenes.
