The 42-year-old actress stepped out for the event on Friday (February 22) Salle Pleyel in Paris, France.
During the ceremony, she took to the stage to honor Karl, who passed away this week at age 85.
“It’s impossible to imagine climbing the steps in Cannes or an Oscar ceremony without one of his mythical creations. His sense of humour and worldview, often hilarious, will be missed. I miss him, I miss him terribly,” Diane said.
Diane also recently revealed on her Instagram that she had come to Paris to introduce her daughter to Karl but it was too late by the time she arrived.
