Katherine Heigl is known for speaking her truth, but after letting her walls down during a Variety Actors on Actors interview with Ellen Pompeo, she allegedly went into full freakout mode. "Katherine Heigl really went there and then was in a huge panic afterwards that she'd said too much," Variety Editor-at-Large Kate Aurthur claimed during the Thursday, December 11, episode of the "Viall Files" podcast, recounting the 2023 interview between the Grey's Anatomy costars.
