'AGT' judges Heidi Klum, Sofia Vergara's strained friendship behind the scenes

America's Got Talent judges Heidi Klum and Sofia Vergara reportedly aren’t friends and only act friendly for the camera.

According to a source, Sofia and Heidi are nothing alike, especially when it comes to their eating habits.

The Modern Family alum joined the show as a judge in 2020, while Heidi has been a constant since 2013.

"They are civil and go online with plenty of showy selfies, but that's as far as it goes," an insider dished to the National Enquirer.

They added: "They don't have much in common besides their jobs on America's Got Talent and don't share the same tastes in style, mannerisms and especially food!"

Sofia, who’s known to be a foodie, has irritated the supermodel with her eating habits: "Heidi has dieted most of her life and she's strict about what goes in her body," the source said. "A meal for her is raw veggies and fruit, while Sofia loves to eat and makes a big show of it, almost like she's rubbing it in Heidi's face!"

They added, "People wonder how Sofia stays so slim given the amount she eats!"
