The 62-year-old director admitted to being devastated by the news, describing Teri as a "legend" and "one of [his] comedy heroes".

He wrote on X: "Oh man, this is devastating. Teri was a legend. So funny, so beautiful, so kind. I had the honor of working with her in 2006 and she was everything I dreamed she would be. Truly one of my comedy heroes. I couldn't have loved her more. This is such a loss. (sic)"
