To prepare for his latest turn as Thor in Avengers: Endgame, Luke told the Daily Telegraph that Chris switched to a vegan diet, with smelly results.
"He went to the toilet a lot more - legumes and beans if you eat a lot you do get very gassy and bloaty," Luke spilled.
We really feel for his wife, Elsa Pataky.
Luke said his mate and client consumed at least 3,500 calories a day, and turned to pea and soy burgers instead of meat to fuel his plant-based diet.
His change in diet came about after he had a "meltdown" after watching the documentary What The Health.
Chris' brother Liam and his wife Miley Cyrus are two of Hollywood's most famous vegans.
But the big question is, is Chris still gassy?
According to Luke, the pair were taught a clever trick to combat flatulence at the hands of beans.
"Use seaweed paper and soak the beans in water and that helps the gassiness," he explained.
